Here's the thing with Murray's play from the pocket. As long as he has a clean pocket, he's fine. He has some accuracy issues, but overall, he's fine. It's when he is met with pressure that he tends to start bailing the pocket instead of standing tall and going through his progressions. He leaves a lot of throws on the field because of this.
The thing is, most of his fans don't want to see that because in the Big 12, he wasn't pressured all that much. I can show you clips from several games of his though where he shows that he consistently drops his eyes vs pressure and looks to get out of the pocket.
I also think that, due to his size, he has a tendency to fade back in the pocket instead of step up or step into his throws.
Sure, let's take a look at him struggling vs pressure. I'm curious.
