Yeah well ask Cam Jordan about that.
He looked like an entirely different player once he dropped that 10lbs or so of extra weight. And 10lbs of muscle translates to a lot of power in many cases like with Clay Matthews' added bulk of 10+ lbs from USC to Green Bay.
Margus Hunt was an even bigger, stronger and faster freak than Aruna but if you play too high and upright then none of it matters. I liked Hunt at 3-4 olb coming out too because of his measurables but he hasn't gotten the opportunity to play there.
I think Aruna's height at 6-6 might limit him from becoming a player like Danielle Hunter because it hurts his leverage. I think that Josh Sweat might have a better chance to play like Hunter or Robert Mathis at LE because he is shorter and his speed and lack of bend would hurt him less there.
Aruna on tape reminds me of a fast Bobby McCray.
