Really? This was written on his draft profile:
"Arm talent and strength are below average"
BTW, I'm not trying to say that he can't be a good QB because of it.

Its hard for me to say what someone else saw that would make them write that, but any time Ive watched Rosen, whether in college or last year with the Cards, Ive always been impressed with his arm strength.
