Definitely Steelers. The 49ers might get a little more running room with James Harrison suspended, but they rely too much on a running game and the Steelers are pretty tough on the run.
I am praying the Steelers D and/or special teams gets a TD or two cuz I am in desperate need in my fantasy playoffs!?! I will need a miracle, but not down too far where I have no hope. I'm down 12 points, but the other guy has the 9ers K Akers going. So realistically no hope, but Polamalu gives me that 1% chance! LOL
