Allen is a better pro prospect than either Reed or Robinson from this year's draft (even though the comparison to Robinson is difficult across positions). He's a perfect mold 3-4 DE. It was surprising that he even decided to come back to Alabama for another year, but it will likely benefit his draft stock barring a catastrophic year on the field for him. He was a massive difference maker on Alabama's 2015 team. While we're on the topic, there's a few other Crimson Tide players being discussed. I've seen Tim Williams, Eddie Jackson, and Reuben Foster mentioned in this thread.
Eddie Jackson is a Safety (Converted from Corner last season) who had a promising 2015, consistently flashing plus ball skills. His ability to cover ground and create turnovers is a plus. However, he lacks ideal size as an NFL Safety, and is an inconsistent tackler. That said, he isn't a bashful tackler either. He's physical for his size, but this doesn't always translate well to the NFL. Matt Elam had a rap as a big hitter in College, and struggled to tackle consistently in the NFL. I think Eddie Jackson is certainly somebody to keep an eye on, as he could have a big year. I'm not 100% convinced he would be a fit for our defense at this juncture though. His stock will fluctuate between the 1st and 3rd rounds depending on his performance.
Reuben Foster is a thumper of an ILB with plus athleticism. He needs to show improved form to allay serious injury concerns in 2016. He will undoubtedly be Alabama's go-to LB, and whether or not he can fill McClain, Hightower, Mosley, or Raglands shoes is yet to be seen, but it will show itself in 2016. In my own opinion, he's not yet showed the proper instincts to play ILB at a high level, and has made up for it with pure physicality. He's been helped out by high level talent around him, but I think this year he'll be the talent others will hide behind. He's a great downhill LB, but actually showed some ability to range. Just watch his kickoff coverage highlights. I think he's a more physical, less cerebral version of CJ Mosley, which I think would make a good compliment to CJ. He'll be a first round pick next season. If we haven't addressed ILB by this time next year, I think I'm in favor of this pick. My only reservation is his health. This dude loves to destroy human beings and take on blockers. He's going to have a big year.
Tim Williams is scary. This is a good thing. He was a one trick pony in 2015, but teams still struggled to stop him on 3rd down. He's a faster version of Noah Spence. If he explodes in 2016 I expect he'll come off the board very early in next year's draft. That said, of all of these Alabama prospects Tim will be the most volatile. Like I mentioned earlier, he was a one trick pony in 2015. He will have to show an ability to stay on the field in run situations this season, and he'll get his chance. This kid is a freak pass rusher, no doubt. But he's never shown an ability to do anything other than come off the edge, which makes him a questionable fit as a 3-4 OLB.
