Ed Bouchette tweets that the Steelers' starting offense and defense will play for about a half, give or take, so we'll see a lot more of Ben Roethlisberger and company than we did in the Steelers' preseason debut against the Redskins. New wide receiver Jerricho Cotchery will make his Steelers debut, and will need to begin establishing himself in the Steelers' offense - Mike Wallace and Hines Ward are the Steelers' starters, and Antonio Brown is quickly emerging as a terrific option behind them.
Beyond that, what I'd hope to see is simply for the Steelers to play better. Their matchup against the Redskins was just a preseason game and isn't necessarily a matter of grave concern, but it's still fair to point out that the Steelers did not look like a Super Bowl team, or even an average NFL team. A couple players (Brown, Isaac Redman) who entered the game with something to prove played well, but most of the team did not.
