It will be hard for them not to give it to Herbert. Not that Caldwell and Burroughs aren't in the discusssion. Herbert undeafted and No takedowns against him. Caldwell technically has 2 losses (All-star vs Metcalf and Med FF vs Terry). Not that Darrion didn't have a fantastic season. I just think Herbert is a lock.
I haven't looked at Burroughs stats. So, I can't break down how dominate of a season he had.
