I'm afraid this just may be another way of basically saying he's got a ton of heart, has been coached up extremely well, but he's just not all that talented. At least not talented enough to make it in the NFL. Also, he's about 35-40 lbs. lighter than the average weight of NFL DT's. His height is above average for NFL DT's though. He's only 5 lbs. heavier than the average weight of NFL DE's, but lacks the speed to play that position.
I truly hope he has a long lasting NFL career, but I highly doubt it. I just don't see where he fits in on a NFL roster. He just doesn't have the measurable's, nor the elite talent for his particular position.
I know, I know, have at it....negavol, etc.
