I say stick with Alex Smith. He had played very well and we have a winning formula with him. Kaep played good for 1 game, but who's to say he's going to duplicate that brilliance again? He is still a 2nd year player and he will get tested, he will have coverages he gets fooled on, he will have Defensive Coordinators who will better prepare for his mobility.
With Alex Smith we went to the NFC Championship game, why take him out now?
With Mark Sanchez the Jets went to the AFC Championship game TWICE. Who cares?
