Rosen did actually hurt himself (he should've thrown the ball out of bounds) by trying to extend a play. But he WAS a sitting duck out there, and it was only a matter of time before he would've gotten destroyed. As for his mobility in the pocket, it's average at best. He has happy feet and doesn't do all that well under pressure. He has a cannon for an arm but he's lost his touch on the long ball -- which he seemed to have as a freshmen. The guy has a LOT of work to do.
