The Jets are likely to play a decent amount of man coverage, and with that, they'll use strong safety LaRon Landry on Miller. That's a favorable match-up for Miller due to his size and athleticism, making him a player to watch today for the Steelers.
With the absence of Jets cornerback Darrelle Revis, and the probability of the Jets sticking true to their man coverage philosophy, Steelers quarterback Ben Roethlisberger will have opportunities to get the ball down the field to his big-play receivers. He's going to need to be sharp with his decision-making and not force throws the way he did against Denver in Week 1.
Making his second consecutive start, Mundy will likely be tested by the Jets' potent offense. With the amount of motion the Jets will employ while showing power running formations, they will likely add in a lot of play action passes with a deep option looking to catch the aggressive Mundy out of position against the pass.
Replacing outside linebacker James Harrison for the second consecutive game, Carter is going to need to stay disciplined, particularly when back-up QB Tim Tebow enters the game in their Wildcat package. In Week 1, they had Tebow out of shotgun and brought a triple-option look. They motioned a slotback toward the strong side, and gave Tebow the option of handing it off or running in that direction with the running back behind him. It wouldn't be surprising to see them plan to run that at Carter, testing his ability to keep the edge.
The offensive line needs to rebound from a less-than-stellar performance in Week 1, and the success of the offensive line, particularly on the ground, can be influenced more by Pouncey than anyone else. The Jets blitz constantly with their linebackers, and Pouncey will need to identify that and be able to reach them on the second level if the Steelers are to run the ball with any success.
