Recently I didn't have much time to dig into other tapes but the MSU, Cle, Ore, Penn St, but I couldn't find many situations of him winning around the edge.
If you do, please post them because I must have missed on them. His outside rip move is just bad because he lacks the explosiveness, balance and bending to perform it effectively.
When he gets the snap count right and swim his way between the G and the T he can be very dangerous.. but what he's missing are the essential skills to be a great 3-4 OLB. I'd rather try to trade back and get any guy like Floyd, Dodd in the 15-20 range who can give me what we're missing (explosiveness, bending) or wait until the second round and get Shilique or Fackrell; or even Schobert/Striker on day 3.
Bosa would add some talent to the Dline but I find him more valuable inside, where his technique and moves have proven to be more effective.
Against the run he missed more tackles than any other pass-rusher I've seen yet.. even when he's able to control his gap and the RB runs right into his arms he's not as effective as you people make him sound like. He even overruns many more plays you would desire for a top 10 pick.
Calhoun, on the other hand, is not as flashy but he does his job. You'll never see him out of position. He possesses a higher football IQ, reads the screens with anticipation and takes good angles to cut those lanes off.
Again, if anyone can show me that he's capable of winning around the corner on a constant base, please show me. I'm always willing to change my idea on things if what comes to light is convincing enough. I'm honestly trying to be as much unbiased as possible, even after his classless twitter rants and the unsalted interviews.
