Superfreak athletes at EDGE that have some pre-reqs like athleticism and run defense...the NFL thinks they can get them to be better sack artists with better scheme, better role, etc. It works sometimes.
I think Stewart is pretty good...I think he's got a relatively high floor as a run defender and athlete. The upside is the sack total...the NFL thinks they can get this out of guys like Stewart. Can the Bengals? The Jags, Ravens, and Packers were able to get it out of their R1 picks. Lets see if the Bengals can do it.
