Draft class. I've read three or four reviews about him and read things like:

Best RB in last decade
Instantly one of top five RBs in NFL
Freakish athlete with unmatched combination of size and speed
here's one word for word:
A rare talent with incredible athletic ability, Barkley’s well-rounded skill set will make him a terror on every down at the next level. His rare explosiveness for his size will create serious problems for NFL defenders, and he’ll be a dream for any offensive coordinator or quarterback who wants a strong running game to balance their attack.
