Kapernick has had more good games in nine starts than Mark Sanchez's has in his entire career. This guy is going to be great, if he isn't already.
Flacco is starting to pull it together in this postseason. He never had the consistency, but seems like he's getting there. He is not elite, but he is at least a pretty good starting QB in this league.
Anyone suggesting that Kapernick and Flacco prove that Sanchez is good enough to win in this league needs to go back and watch the tape.
