You can't blame everything on the line or the coaches when it comes to Rosen. However, I am one of those that is worried about Murray's height. He has never played against line size he will face in his this league. Is he going to be a pocket passer or a running QB in this league. If it's the latter that worries me.
Dan Patrick gushed about what a great running QB Murray could turn into the NFL. Didn't really gush about his passing or pocket presence but his running. NFL running QB's have a very very short window of success and typically don't translate to the NFL.
I know it's not popular but I prefer Haskins over Murray not because I think Haskins is a better athlete. It's because I think it becomes the better QB. That would be my pick.
Either way the Cards have HUGE decisions to make very soon.
