I'm sorry, but the fact that you say the Browns passed on Wentz because they thought RGIII was better is the dumbest thing I've read, and so far from the truuth that it's downright ignorant. They made that trade because they felt the package of picks they got back in return was better than Wentz. Was it wrong to pass on Wentz? Probably. But saying they did it for RGIII is so wrong. They got a first round pick back (which they thought would be high, either way, its a first round pick) AND they still selected Cory Coleman, who looks to be a terrific WR. So yea, you lost a lot of credibility by saying they valued RGIII over Wentz. I'd actually like to know where you even got that idea from.
Summary: Drake Nevis was not able to compete at the Senior Bowl with a minor foot injury. There is really nothing comparable in the draft process to competing against other high level prospects so it is unfortunate he was unable to do so. He was surrounded by a lot of future NFL players on the defensive line at LSU which prevented him from gaining more starting experience. His value is as a disruptor and penetrator who can wreak havoc, probably as a rotational player in a 4-3. He is unlikely to stifle the run and will need to be supported by complementary players.
Player Comparison: Trevor Laws. The obvious link here is being undersized, but both guys showed the ability to get through traffic at the college level with similar speed. Nevis is more of a pass rusher and certainly will not record his first sack in his third season as Laws did this year.
