Aaron Leming’s Top 5 Most Improved NFL Teams Heading into 2025
As the NFL offseason draws to a close and teams transition from the hypothetical world of free agency and the draft to the tangible reality of minicamps and the looming threat of training camp, the perennial question arises: Which teams have truly positioned themselves for a significant leap forward? Renowned NFL analyst Aaron Leming has weighed in with his definitive list of the five most improved teams heading into the 2025 season. His selections highlight strategic overhauls, shrewd talent acquisition, and a clear vision for competitive resurgence, painting a compelling picture of potential shifts in the league’s landscape. From burgeoning offensive powerhouses to defensively fortified contenders, these five franchises have, according to Leming, laid the groundwork for a dramatically different outlook in the upcoming year.
1. Carolina Panthers: Building from the Trenches Out
The Carolina Panthers, a franchise that has endured significant struggles in recent years, appear to have embarked on an offseason transformation aimed at establishing a more competitive foundation. Leming identifies the Panthers as one of the NFL’s most improved teams, emphasizing their dual focus on shoring up both sides of the ball, particularly in the trenches.
Their key free agent additions speak to a deliberate strategy. On defense, the Panthers brought in safety Trevon Moehrig, a versatile defensive back who can provide stability and playmaking in the secondary. The additions of defensive ends Patrick Jones and Tershawn Wharton, alongside defensive tackle Bobby Brown, are designed to bolster a defensive line that needed significant reinforcements. These experienced players are expected to immediately contribute to a more robust and disruptive front, aiming to elevate the Panthers’ defense closer to league average after years of inconsistency.
The draft further amplified this defensive focus. With selections like wide receiver Tetairoa McMillan (Arizona), defensive end Nic Scourton (Texas A&M), defensive end Princely Umanmielen (Ole Miss), and safety Lathan Ransom (Ohio State), the Panthers addressed core needs with promising young talent. Scourton and Umanmielen, both high-upside edge rushers, will complement the veteran additions on the defensive line, providing a future pipeline of talent. Ransom, a physical safety, adds to the depth and versatility in the secondary, working alongside Moehrig to tighten up the back end.
Offensively, the Panthers prioritized giving their young quarterback more support. They successfully retained veteran wide receiver Adam Thielen, a reliable target who provides a consistent presence in the passing game. The significant addition of Tetairoa McMillan, drafted early, gives their offense a legitimate threat in the receiving corps, bringing size and contested-catch ability. In the backfield, running back Rico Dowdle was brought in to complement existing back Chubba Hubbard, aiming to create a more effective and versatile running game. The collective impact of these moves is a deliberate effort to create a more balanced and capable offense, allowing their developing quarterback to operate with greater efficiency and a more diverse arsenal of weapons. The Panthers’ offseason strategy, according to Leming, signals a comprehensive approach to building a more competitive team, starting with the foundational elements of the offensive and defensive lines and gradually expanding outwards. The hope in Carolina is that these calculated moves will finally translate into tangible improvements on the field and a more positive trajectory for the franchise.
2. Chicago Bears: A Comprehensive Overhaul for the Caleb Williams Era
Perhaps no team has generated more offseason buzz than the Chicago Bears, and Aaron Leming’s inclusion of them on his list of most improved teams is hardly a surprise. Their transformation, driven by a new coaching staff and aggressive talent acquisition, has been one of the NFL’s most active and comprehensive. The Bears’ offseason began with the hiring of former Detroit Lions offensive coordinator Ben Johnson as head coach, a move that immediately signaled a new philosophical direction for the franchise. Johnson’s arrival set the tone for a period of significant change that extended deeply into free agency and the draft.
General Manager Ryan Poles, working in tandem with Johnson, executed a balanced approach, unlike some past offseasons where focus was heavily skewed towards one side of the ball. The emphasis was on strengthening both the offensive and defensive lines, recognizing these as critical foundational elements for sustained success. On the offensive line, the Bears made blockbuster additions with interior linemen Joe Thuney, Drew Dalman, and Jonah Jackson. These are not merely depth pieces; Thuney and Jackson are Pro Bowl-caliber guards who immediately elevate the entire unit, providing much-needed protection for franchise quarterback Caleb Williams. Dalman brings a steady presence at center, solidifying the interior. This commitment to trench play is a direct response to the league-leading 68 sacks the Bears surrendered in the previous season, aiming to provide Williams with a clean pocket and time to operate Ben Johnson’s sophisticated offense.
The defensive line also received a significant overhaul. Defensive end Dayo Odeyinbo and defensive tackle Grady Jarrett were brought in via free agency, instantly upgrading the pass rush and run defense. Jarrett, in particular, is a proven disruptive force who will command attention from opposing offensive lines. In the draft, the Bears continued to invest in the trenches, selecting offensive tackle Ozzy Trapilo and defensive tackle Shemar Turner, further solidifying both lines with promising young talent. They also added tight end Colston Loveland and wide receiver Luther Burden III, providing Williams with more weapons to complement D.J. Moore and Rome Odunze, creating a truly dynamic offensive arsenal.
Leming notes that Poles “doubled down on the core built over the previous three years in many ways,” suggesting a reinforcement of existing talent while strategically injecting elite new pieces. When all was said and done, the Bears secured six new starters, with the potential for another three depending on performance in training camp and the preseason. This holistic approach, addressing both coaching and personnel needs across offense and defense, has created a sense of genuine optimism in Chicago. The Bears’ aggressive and calculated offseason, according to Leming, makes them a prime candidate for a significant leap in 2025, finally positioning them to contend in the NFC North and beyond.
3. Jacksonville Jaguars: An Unconventional Path to Improvement
The Jacksonville Jaguars’ offseason was, by all accounts, nothing short of unconventional, marked by surprising coaching and general manager changes. Yet, according to Aaron Leming, this tumultuous period ultimately positioned them as one of the most improved teams. The initial shockwaves included the firing of head coach Doug Pederson, followed by a dramatic reversal of course that saw General Manager Trent Baalke also relieved of his duties after a “rough start to the interview process.” The dust eventually settled with Liam Coen taking the reins as head coach and James Gladstone stepping in as the new general manager. Despite the unusual path, Leming suggests fans should be “happy with the end result,” as the new leadership aims to unlock the team’s potential.
The Jaguars’ free agency period was marked by tactical additions to address specific needs. On the offensive line, they brought in versatility and experience with Patrick Mekari and Robert Hainsey, bolstering the interior and providing more protection for quarterback Trevor Lawrence. In the secondary, cornerback Jourdan Lewis and safety Eric Murray were signed, aiming to improve coverage and bolster the defensive backfield. Wide receiver Dyami Brown was added to provide another option in the passing game. These moves represent a commitment to shoring up various positions with reliable, established players.
The draft was also critical in the Jaguars’ improvement, highlighted by some intriguing selections. Cornerback/wide receiver Travis Hunter (Colorado) was a high-profile pick, bringing rare two-way talent and immediate excitement. Cornerback Caleb Ransaw (Tulane) further bolstered the secondary, while interior offensive lineman Wyatt Milum (West Virginia) and running back Bhayshul Tuten (Virginia Tech) added depth and future potential to the offense. These draft picks aim to infuse youth and athleticism into key areas, complementing the veteran acquisitions.
Leming underscores that a “better coaching staff in the building was the biggest thing they could’ve done this offseason.” The new regime’s ability to leverage the existing talent on the roster, which includes former No. 1 overall picks in quarterback Trevor Lawrence and defensive end Travon Walker, is paramount. Lawrence, in particular, is expected to benefit significantly from a more stable and effective coaching environment. The Jaguars also benefit from being in “one of the softer divisions in football,” which could provide a more forgiving path to contention. By addressing both coaching and personnel, the Jaguars have, despite their unorthodox journey, set themselves up for a more competitive 2025 season, making them a fascinating team to watch.
4. Las Vegas Raiders: The Pete Carroll Effect
The Las Vegas Raiders, often a franchise shrouded in volatility, appear to have found a new sense of direction and stability, earning them a spot on Aaron Leming’s list of most improved teams. The most significant factor in their transformation is undoubtedly the hiring of legendary head coach Pete Carroll. After a highly successful tenure with the Seattle Seahawks, Carroll brings a proven track record of building winning cultures and competitive teams. His arrival immediately injected a new level of credibility and a clear philosophical identity into the Raiders organization.
Carroll’s impact extended directly into the free agency period, where the Raiders made several impactful additions. Quarterback Geno Smith, a reclamation success story under Carroll in Seattle, was brought in, providing a stable and experienced option at the game’s most critical position. Safety Jeremy Chinn, a versatile defensive playmaker, adds athleticism and coverage ability to the secondary. On the offensive line, guard Alex Cappa was signed to bolster the interior, providing better protection for their quarterback and support for the running game. Cornerback Eric Stokes and linebacker Elandon Roberts further reinforce the defense, adding experience and depth to key positions. These acquisitions reflect Carroll’s preference for fundamentally sound, tough, and competitive players who fit his aggressive defensive and run-heavy offensive schemes.
In the draft, the Raiders continued to build on their newfound direction. Running back Ashton Jeanty (Boise State) was a notable pick, adding another talented runner to their backfield, a staple of Carroll’s offenses. Wide receiver Jack Bech (TCU), cornerback Darien Porter (Iowa State), and offensive tackle Charles Grant (William and Mary) further filled out the roster with young talent, providing depth and potential for future development. These picks, while perhaps not as splashy as some, align with Carroll’s philosophy of drafting players who fit specific roles and can contribute to a cohesive team identity.
Leming emphasizes that the hiring of Carroll “raised their floor tremendously.” Even in one of the toughest divisions in football – the AFC West, featuring the likes of the Kansas City Chiefs and Los Angeles Chargers – the Raiders now possess a clear direction and a veteran presence at the helm. While their ceiling might not be immediately Super Bowl-contending, the disciplined approach and winning culture Carroll instills make them a far more reliable and competitive team. The strategic offensive and defensive additions complement Carroll’s preferred style of play, creating a cohesive unit. If all goes well, Leming suggests, “don’t be surprised to see them competing for a Wild Card spot,” a testament to the significant improvements made under Pete Carroll’s leadership.
5. New England Patriots: Rebuilding for a New Era
The New England Patriots, a franchise in transition following the departure of Bill Belichick, have leveraged their considerable cap space and draft capital to orchestrate a significant rebuilding effort, earning them a place on Aaron Leming’s list of most improved teams. The initial shift began with the hiring of former long-time Patriot Mike Vrabel as head coach, following the short tenure of Jarod Mayo. Vrabel brings a hard-nosed, disciplined approach that aligns with the Patriots’ historical identity while offering a fresh perspective on the team’s direction.
The Patriots entered the offseason with an “unbelievable amount of cap space,” a critical advantage they utilized to surround second-year quarterback Drake Maye with the necessary offensive talent. Priority number one was to upgrade the receiving corps and offensive line, two areas that had significantly hampered their offense in previous seasons. In a stunning move, they acquired Pro Bowl wide receiver Stefon Diggs, instantly providing Maye with a legitimate No. 1 target who can stretch the field and make contested catches. This addition alone dramatically alters the offensive landscape. Further bolstering the offense, offensive tackle Morgan Moses was signed, adding a veteran presence and much-needed stability to the offensive line.
On the defensive side, the Patriots also made strategic additions, bringing in defensive tackle Milton Williams and defensive end Harold Landry to bolster the pass rush and run defense. Linebacker Robert Spillane and cornerback Carlton Davis were also signed, adding experience and depth to key defensive positions. These free agent acquisitions reflect a commitment to maintaining a strong defensive identity while injecting new talent across the board.
The draft further solidified their rebuilding efforts. Offensive tackle Will Campbell (LSU) was a critical early pick, providing a potential long-term blindside protector for Drake Maye. Running back TreVeyon Henderson (Ohio State) adds dynamic talent to the backfield, complementing their run game. Wide receiver Kyle Williams (Washington State) and interior offensive lineman Jared Wilson (Georgia) further add depth and future potential to the offense. These draft picks are geared towards building a sustainable offensive foundation around their young quarterback, providing him with a strong supporting cast for years to come.
Leming highlights that the Patriots’ aggressive free agency and draft strategy, coupled with the change in coaching, has created a clear path to revitalizing the team. While the team is still in a rebuilding phase, the sheer volume and quality of talent acquired, particularly on offense, should significantly improve their competitiveness. The goal is to maximize Drake Maye’s development by providing him with the resources he needs to succeed. The Patriots’ 2025 offseason, according to Leming, is a testament to a well-executed plan aimed at returning the franchise to prominence and laying the groundwork for a successful new era.
A Landscape of Resurgence
Aaron Leming’s selections for the five most improved NFL teams heading into the 2025 season – the Carolina Panthers, Chicago Bears, Jacksonville Jaguars, Las Vegas Raiders, and New England Patriots – paint a compelling picture of a league in constant evolution. These teams, each with their unique challenges and strategies, have collectively demonstrated a commitment to significant change, leveraging new coaching philosophies, shrewd free-agent acquisitions, and impactful draft picks.
From the Bears’ comprehensive overhaul around Caleb Williams to the Panthers’ foundational improvements in the trenches, and from the Jaguars’ surprising yet effective coaching changes to the Raiders’ newfound stability under Pete Carroll, and the Patriots’ strategic rebuilding efforts around Drake Maye, a common thread emerges: a focused, deliberate approach to elevate their respective franchises. The emphasis on offensive line play, the strategic acquisition of dynamic playmakers, and the commitment to strong defensive identities are consistent themes across these five teams. While only time will tell how these offseason moves translate into on-field success, Leming’s analysis provides a robust framework for understanding where the most significant positive shifts have occurred in the NFL this year. The 2025 season promises to be a fascinating study in competitive resurgence, driven by the ambitious efforts of these newly improved contenders.
