Mine would be former 2d Rd pick, No. 51 overall, DE DeMarcus Walker. At 6’4" 280, and only 26 years old, he’d fit as a 3-4 DE.
Only started 5 games in his career, so his cost shouldn’t be prohibitive. Showed some pass rush ability with 4 sacks in 2019 and 4.5 sacks in 2020.
Unlikely to be a qualifying FA for purposes of the comp pick formula.
