While Mark Sanchez isn't a huge yardage passer, he does have one trait that many NFL teams would like: He knows how to win in the playoffs.
He's got great wide receivers and they're much better than last years. He's got Braylon Edwards, who sometimes does drop crucial passes, can be a good deep threat WR and could give the Steelers corners some troubles.
Santonio Holmes doesn't have the same chemistry with Sanchez as he did when he played with Ben Roethlisberger on the Steelers. Holmes is a very quick receiver, and I believe him and Sanchez will develop into a great duo.
In my opinion, Jerricho Cotchery is still one of the best slot WR's in football. He's not Larry Fitzgerald, but can be a deciding factor. He's got some good WR's in front of him, and the Jets are more of a running team.
However, I'm not gonna give this entirely to the Jets. They had the 22nd ranked pass offense in football. The Steelers have a great pass defense and when they played the Jets in Week 15, Troy Polamalu didn't play, so him returning will just make it tougher.
