The NFL draft is anything but an exact science.
Twelve months before the 2013 draft, Matt Barkley and Manti Te'o were popular names to go up toward the top. Twelve months before the 2012 draft, Andrew Luck was as sure a thing as one could get, but Robert Griffin III came out of nowhere. Twelve months before the 2011 draft, Ryan Mallett and Da'Quan Bowers were supposed to be locks.
Point is, anything can happen in a college football season. While, right now, Jadeveon Clowney looks like the best prospect this side of Julius Peppers, it's hard to remember that a prospect as fantastic as Peppers went No. 2 after David Carr.
It's also important to remember that Clowney's teammate—Marcus Lattimore—was supposed to be the best running back prospect ever. A knee injury can change one's draft stock in a hurry. Clowney gets that; he's even taken out an insurance policy.
Twelve months out, we have no idea who the top pick in the 2014 NFL draft is going to be, but the field of candidates couldn't be any more exciting.
