You've been given a primer on the players to watch and those with something to prove, and now here's the rest of the lists:
Top five to watch
3. USC S Kevin Ellison -- A knee injury cost Ellison the final five games of the season and teams will want to see how far along he is in the recovery process. When healthy he is a big hitter who fills hard when he reads run and punishes receivers over the middle. Though he lacks ideal top-end speed he changes directions well for his size and he showed underrated man-to-man cover skills before the injury.
4. Oregon OT Fenuki Tupou -- The 332-pound Tupou doesn't have prototypical initial quickness for a left tackle and he's going to have some problems preventing premiere NFL edge rushers from turning the corner. On the other hand, he has the size, athletic ability and strength to develop into a starting right tackle at the next level.
