Nationally recruited RB Andrew Cunningham has Purdue in his final 5. Watching his videos he would be a major asset to the class and to the program. Great size and speed and pass catching ability out of the backfield...however, I can't help but think he would be a monster at OLB in college and potentially the NFL. Legit 225 right now and could easily put on 10-15 more pounds to become a very sturdy and agile OLB with an ability to cover in space.
Looking at his offers, I think many higher programs (Alabama, Georgia, etc) probably saw him as a SS or OLB but he has his heart set on RB in college. That gives Purdue a chance at a very sought after recruit.
