The bigger issue on Murray (no pun intended) is whether he would be committed to football. Will he play both football and baseball? Does he prefer one over the other?It's difficult for you to see the top QB in the draft going before a guy who's 5'9?
I like Murray, he's got a rifle for an arm and he's a great athlete but size is as important as anything in the NFL. When you are THAT small, and yes he's tiny for a starting QB, you won't last in the NFL.
Yes, I think his height is an issue as well. I also think Haskins will be the first qb taken, but that's just my opinion.
