Why do people keep saying he has all this athleticism? 

I guess he can do 13 back flips, but his acceleration, jumping, and lifting numbers at the combine were in the bottom half of DE's at the combine.  (you know the traditional indicators for an edge rusher).

I look at this guy and see a lack of game tape, and mediocre scouting reports for what tape there is to watch.  But he's a first rounder because of athletic potential.  Then I look at his workouts and see 59 KEI and 1.65 through the 10yd split and wonder what am I missing that people have this guy as some kind of specimen.
