Your Pick for the Best Prospect of the 2015 NFL Draft?

Regardless of team needs, who do you think is the best prospect of the 2015 NFL Draft?Right now I actually believe Amari Cooper is ahead of the pack.  In him I see a future perennial pro bowl wide receiver, though I recognize taking a wide receiver at the top of the draft is strikingly unusual.  (In other words, I understand and support why the Bucs will most likely take a QB, LT or DL with our pick).What say you?
