Don't forget fumbles. He has gotten better at hanging onto the ball after minor contact, but expect that to change when he gets knocked around a little bit behind a line that probably won't be as good as SF's.
Smith is a great game manager. And I don't use that term in a derogative fashion. Alex has maximized the talent he has. Not his fault the 49'ers went the seemingly safer route with a QB who was more advanced than Rodgers was on draft day. Smith is Trent Dilfer. He's a QB who will make all the safe plays and generally not cost you the ball game. Just don't ask him to throw the ball deep. Don't ask him to perform under duress. Smith needs to make a living on throwing 5 yard passes. The problem with that is CB's and safeties, even LB's are now fast enough to prevent a receiver from getting 2 yards after the catch on a 3rd and 7.
