The Detroit Lions are no strangers to finding stars in the NFL Draft and the immediate aftermath, having turned over plenty of stones to ensure they can build a roster that can bring the city its first Lombardi Trophy.
While the Lions fell short in their pursuit of the Super Bowl last year, they still have the fifth-best odds (+950) at FanDuel Sportsbook in 2025, and fans should expect another competitive season.
General manager Brad Holmes has been active in the undrafted free agency market, and he just spent quite a bit of money to bring one specific player’s services to Detroit.

Lions Sign Undrafted LB/DL Keith Cooper Jr. in Big UDFA Deal
According to NFL insider Aaron Wilson, the Lions signed Houston Cougars undrafted free agent Keith Cooper Jr. He’s a hybrid defender with experience at linebacker and defensive line.
The Lions gave him a $20,000 signing bonus and $125,000 guaranteed, representing one of their largest investments throughout this undrafted period. They clearly wanted him, yet faced competition, but now the intriguing athlete is in Detroit.
During his four years, three of which were spent at Tulane prior to transferring to Houston, Cooper had 119 tackles and 14 sacks, deflecting eight passes in coverage as well. He can contribute on special teams, and his athletic profile suggests there’s untapped potential waiting to be unlocked. “Tweeners” often find a hard time securing a place in the NFL, yet head coach Dan Campbell’s system suggests Cooper might shine in the summer.
Nonetheless, he faces an uphill battle to make the roster. Detroit is deep, and it’s difficult to lock down a spot on that 53-man group. Nonetheless, Cooper’s production and 6-foot-4, 259-pound stature make him someone who could be a developmental prospect on the practice squad. Perhaps in 2026 or 2027, Cooper could make a difference.
For now, it’s a worthy dart throw for a Lions organization that has become renowned because of their successes, mirroring what Cooper may become.
