He's not a speed rusher so you won't see him turning the edge like Wake. What he does do is push his man back into the quarterback.
He'll be fine.
Meh. That doesn't require talent in a pass rushing sense as all Misi has is a bull rush.
Misi only had 1 sack over the final 10 games last year. That's because once teams studied him after a couple games into the season, he was easy to stop on the pass rush with such a limited arsenal in his repertoire. Misi is good in coverage and decent against the run. That's it.
In a 3-4 defense, you want pass rushing talent from your OLB's, first and foremost. For a high 2nd round pick, the guy better have pass rushing talent. You can find guys like Misi that are decent against the run and in coverage in later rounds.
If Misi doesn't develop a good pass rush, and I don't think he can as he doesn't have the physical ability to turn the arc at full speed while sinking his hips, then it wasn't a very good draft selection considering where he was taken
