Not only that, but some quarterbacks are playoff-ready and some are not. You could see it all through the weekend, QB's that play badly under playoff pressure.
Say what you want about Mark Sanchez, but he's money in the playoffs. 60% completions, 9 TD's to 3 INT's, QBR of 94.5. 4-2 record. Arguably the best Jet on the field in the two losses. 6 playoff games, not a bad one yet.
It's the primary reason I want him to get a legitimate second look in a new offense. There's no point in going to the playoffs if your QB isn't capable of handling it once he's there. Mark Sanchez has cleared that hurdle.
