Can't wait for the game to start.
For me, at least for tonight, I am not too worried about establishing a strong running game. Offense 101 tells you to attack a defense at its weakest and to use where you are your strongest. For the Steelers, their secondary is the weak point, and the Redskins' strength is their passing game.
If the Redskins can get a strong running game going, then great. However, the Steelers had a good run defense last season, and it is pointless for the Redskins to try and batter up against it, only to keep putting themselves into 3rd-and-long situations if their run game isn't working. They will probably use a short passing game to the RBs in place of a running game to keep the drive moving if there are no running lanes.
Do what they did best in the second half of last season, and they can win this game.
