I've watched enough of McCarron at the college level to get the impression he could at the very least manage and win football games with a good D at the pro level in my humble opinion.
I understand why A J's small body of work in the NFL has many Bills fans skeptical. On the other hand though I look at adding a young signal caller like McCarron as giving Buffalo not one, not two, but three possibilities to hit pay dirt along with Peterman and a high round rookie.
