Cousins has the arm to make any throw (excluding what Mahomes does) and when he and the O are clicking it is really good. I wish he was a quicker, more elusive runner but that is not a necessity with a decent OL, and he is what he is. My concern is what goes on in his head. Going in he seemed to be somewhat unusual, but all that is ok - and even complimented - when the team is winning. Still, I think he puts too much pressure on himself, and that manifests itself in plays where the pocket is collapsing and in too many cases he doesn't prevent a negative thing like a strip sack, a sack, pick six, etc. He seems like a completely rational or logical person, but under pressure he behaves irrationally. Maybe he has hired another specialist to the stable who is helping him calm down, chill out, whatever.
That said, with the sieve that is the OL it is not surprising those things occurred, and I think occurred more frequently as the season went on.
I suspect he will be better in this regard because he knows it is a flaw and the OL 'has' to improve. I mean, it has to. It just does. It will, right?
