He lacks a great first step and doesn't reach the corner. A majority of his sacks came from quarterbacks holding on to the ball for too long. His upper-body is extremely skinny, skinnier than that of Gaines Adams and even Michael Johnson. He isn't fast at all and looks like he will run a 4.8 or a 4.9. Honestly I think he is the worst of all of the prototype defensive ends (Peppers, Williams, Anderson, Johnson, Adams). He compares favorably with Jamaal Anderson from a few years ago who went top 10 and hasn't done anything in the NFL, the only difference? Jamaal Anderson was better in college and was stronger.
IMO the best prototype DE in this draft is Corey Wootton out of Northwestern.
Dunlap does have his positives though, he does have a nice bull rush, he has nice production and he never quits on a play. However I think that his strength and bull rush are results of playing against College Left Tackles that are not NFL caliber. In fact, he played 3 first round NFL tackles in Andre Smith, Michael Oher and Ciron Black all 3 of whom are right tackles in the NFL. Do you know how many sacks he registered against them? Not one. He didn't even get a sack against Phil Loadholt.
The depth chart I found said he played RE but it could be wrong so I'll just name the RTs he faced in those games:
Drew Davis, John Jerry, Joseph Barksdale and Trent Williams. 4 players who will be in the NFL, he did not register a sack.
He did not register a sack in 8 separate games. And he compiled 6 of his sacks against the likes of Kentucky, Florida St. and Miami. The only notable LT on these teams is Jason Fox, who I believe had a freshman QB that he was protecting. But aside from that he beat up on a freshman and a no name at Kentucky.
And it looks even worse if he was a LE because he was going against nobodies versus Florida St. and Kentucky and he played against an injured Reggie Youngblood in Miami. Not good any way you spin it.
Here is an example of what I mean by he gets sacks because the QB holds the ball too long:
