Newton will be a slightly better version of Vince Young if everything breaks his way, which it won't in Carolina. I'm actually not as down on Ponder as others - guy is a decent QB who can move around. Locker will be a bust, and Gabbert looks like a Joey Harrington-type: looks like a QB but might not have it all together.
I'm high on Mallet - kid can make the throws and has a little edge to him. I doubt any of these QBs will be top-3 in the league at any point in their careers, but I expect Mallet to be breaking WRs fingers for years to come. Also, Tacopants will be going in the bottom of the 2nd - book it.
