I think Quinnen Williams is in a weird spot because I think the same reasons he was evaluated a little low coming out of high school are likely to affect his draft stock after they get all the measurables in the combine meat market. He almost certainly got a first round grade. He will probably go in the first round but I don't think he's going to go as high as the media draftniks think. I think he's going to "fall" to the back half of the first round.
Q has maxed his potential. The only thing he could do to improve his stock is better fitness but frankly he doesn't have much weight to lose and be an effective interior linemen in the pros. Can he really improve that cardio/fitness aspect without hurting his ability to hold up at the point of attack (which isn't his best attribute as an interior linemen anyway)?
This is a DEEP DL draft too. He's gonna get picked apart for how he's not a prototypical DT and maybe reached the peak of his athletic ability. He could even drop out of the 1st depending on team needs. He's got one big thing going for him though: Aaron Donald. This year, Donald put a serious scare into the single-season sack record from an interior position. The NFL is a copycat league and people may say "he might not have untapped potential but what he is fits what we need."
