It's a silly, tough love post, but worth considering. Yes Cousins had a cockiness and swagger about him that I wish Trevor had. But...

A. Pressure up the middle is a different animal than the edge-- there is no pocket to step up into. See Brady in the 2015 AFCCG. or Newton in the SB. Garcia is a dumpster fire. Can't defend the bull rush or the stunt. 

B.  For every QB he listed with foot speed and escapability, there is a HOF QB who lacks that element to his game. Manning, Stafford, Ryan, Rivers and Brady all come to mind. It's not an excuse -- the dude is never going to be a quick runner.  

C. Though his pocket awareness has got to improve this season. In week 1/2, he moved around in the pocket and extended some plays while keeping his eyes down field. That skillset dissolved the past two weeks -- it's up to McCoy to do what they always said he is good at: design an offense that mitigates the weaknesses of the QB and OL.
