Kiper has a couple of SEC players on both of his list. Here's what he had to say about each:
Cordy Glenn's flexibility to play multiple positions on the offensive line should make him an attractive prospect.
Cordy Glenn, OG, Georgia: "Considering I have Glenn as a mid-first-round pick best suited for guard, it's hard to say he could move up, but some teams could probably see him at right tackle, too. Workouts confirmed what we believe -- powerful yet plenty nimble for his huge frame."
Thoughts: Glenn has the athleticism to have success at the next level. Plus, his versatility should really help him because he can play multiple positions, which is certainly a plus for teams. He has the ideal size to play inside, but teams know he can play outside, which could help him rise in this draft, as Kiper said. I don't see him falling out of the first round.
Fletcher Cox, DT, Mississippi State: "Solidified a mid-first grade. It won't say a lot about what he does on the field, but a 4.79 at 298 pounds is a pretty freaky number for a DT. Good week for Cox."
Thoughts: I knew Cox was quick and fast on his feet, but I didn't know he was 4.7 fast. He's powerful and showed last season that he can really wreak havoc in opposing defensive backfields. If not for a tremendous showing by Memphis' Dontari Poe, Cox might be slated as the top defensive tackle available in the draft.
Alshon Jeffery, WR, South Carolina: "He checked in at 216 following three years of being listed about 13 pounds heavier. If he doesn't run at about 4.5, we'll certainly wonder if he has enough athleticism to separate. He's a big target and it'd be hard to see him falling past the second round, but he has work to do."
Thoughts: I've seen Jeffery play time and time again and I've always come away impressed when he's in one-on-one situations. He's incredibly physical and really makes a corner's job much harder in jump-ball situations. He's not the fastest receiver out there and last year's dip in his production could hurt, but you can't forget about his ability to manhandle defenders.
Michael Brockers, DT, LSU: "Up to 322 pounds, Brockers is still seen as a 3-technique tackle in a 4-3. But the weight seemed to drag on his explosiveness, and the strength numbers were also less than average. He may want to drop a little weight before his pro day. Still a safe Round 1 guy, but needs to find that comfort zone."
Thoughts: He wasn't very impressive at the combine, but like Jeffery, he showed how well he can play during his college days. His field speed was certainly better than what he showed at the combine. I think his stock has fallen, but you have to think that what he did in 2011 will make sure he stays in the first round. He certainly can't falter again during his pro day.
Courtney Upshaw, OLB, Alabama: "He's a high-motor guy who can rush the quarterback, but he didn't run in Indy and will need to show enough explosiveness that teams think he won't get engulfed by NFL tackles."
Thoughts: Whenever you skip out on workouts questions will arise, but from everything I've heard, he will probably be the first outside linebacker taken in April's NFL draft. He showed all year that he has the speed to be dangerous on the outside.
