Maybe in college, but not in the Pro's. They only last a few years in the Pro's, 1st injury they're done. It'll never work in the Pro's, they're just too quick and talented on defense. Can't tie up that much money in a QB who could possibly get hurt on every run.
It's not just about tying up money. If you wear out your quarterbacks faster that will affect your drafting as well since you'll need to draft more at quarterback to make up for the injuries. And drafting quarterbacks can be a crapshoot. On the other hand, in college, a guy isn't going to play more than four years anyway; so you don't worry so much about him getting injured.
