Three-technique with impressive athleticism and movement skills, but a lack of play strength to hold up at the point of attack. Collins needs to play for a defense that allows him to play up the field and should benefit from pass rush work with NFL coaching and teammates. Collins should test well which could push him way up the draft board, but his floor is lower than many of the defensive tackles in this draft.
His draft grade will likely be higher than his 2015 tape would indicate due to a high ankle sprain that limited his overall play and production. Valentine needs to carry more "good weight" and commit to the work that has to be done leading up to the game. If he can do those things, he has enough power and ability to become a backup nose with eventual starter potential.
