1Keep Ben standing: The Cardinals aren't a great pass-rushing team. They got to opposing quarterbacks just 31 times this season. But the Steelers' offensive line has had its problems protecting Ben Roethlisberger. He was sacked 46 times this season. The only quarterback who got sacked more was the Patriots' Matt Cassel (47). Twenty of those 46 sacks came in the Steelers' four lossess. If his line keeps the rush off Big Ben, he should be able to do some damage to the Cardinals' defense.
2Many happy returns: One of the Cardinals' weaknesses that the Eagles weren't able to capitalize on in the NFC Championship Game was their poor coverage units. They were near the bottom of the league in both punt coverage (13.1) and kickoff coverage (25.0). Steelers punt returner Santonio Holmes averaged just 6.6 yards per return in the regular season, but has been hot in the playoffs. He's averaging 19.6 yards per return, including a 65-yard return for a touchdown against the Ravens.
3Here's looking at you, Kurt: Most of the blitzes the Eagles used against Kurt Warner in the NFC Championship Game came from the outside. He did a good job of picking them up, stepping up in the pocket and getting the ball out before the pressure got to him. But Warner isn't very mobile and has difficulty getting to the outside. So look for the Steelers to focus more of their blitzes in the "A" and "B" gaps, where they can get in his face and not allow him to step up and avoid that outside blitzer.
4Early run success: Willie Parker missed five games this season with knee and shoulder injuries and averaged a career-low 3.8 yards per carry. But he's healthy now and has had 100-yard rushing performances in two of the last three games. If he can get going early against the Cardinals, it will open things up for Ben Roethlisberger and the passing game and keep Arizona's defense guessing.
5No YACking it up: Larry Fitzgerald, Anquan Boldin and Steve Breaston combined for 262 catches and 3,475 yards this season. They're going to catch some more passes Sunday. What the Steelers need to do - what the Eagles failed to do - is minimize the damage. Limit their yards after the catch. That's where Fitzgerald and Boldin can really kill you.
