Sanchez on the Steelers Dan Leberfeld

Mark Sanchez knows the Jets challenge on Sunday, in Pittsburgh, is enormous.

“We saw them come back in the third and fourth quarter [against Baltimore],” Sanchez said. “You’ve got to beat them. You can’t let up, l[with] their coach, their quarterback, and their defense. It’s going to be a fight to the finish.

“We’re both one step away from where we ultimately want to be, so it’s going to take our best effort all week long. We’ll be ready for the game.

“It’s going to be in a tough environment again and it’s good that we have the experience of playing there because we’re going to need that.”
