Don't know that the NFL.com folks think "great". Also where they think he'd be drafted. I know one can find a diversity of opinion, but since this was right on the page...
Weaknesses Slow twitch with borderline play speed. Must transition from a power mindset to a little more quickness in everything he does. Will need quicker hands to jab and separate to stay clean against NFL linemen. Below average lateral quickness. Won't win many foot races to the perimeter and has little margin for error with his angles. Not athletic enough to recover if he gets hung up on a block for too long. Too easily fooled into vacating his positioning by play-action. Doesn't have reactive athleticism to quickly recover back into his duties after biting on fakes. More of a block occupier than serious threat when blitzing. Average awareness dropping into zone coverage. Situational awareness needs work.
Draft Projection Rounds 5 or 6
