I'd have to go back in read my original post, but I think I probably owe a mea culpa.
I believe what I said was that on paper, it looked like a comfortable win of 4-7 points for the Steelers unless we could do two things: go at least +1 in turnovers and win the red zone battle.
We did both. I think I'd argue that the pick six was the play of the game. It's hard to say that when the score was 23-3 going into the fourth quarter, but the reality is that by that point in the game, they'd figured out our defense and they were shredding us without using hardly any clock time at all. At that point in the game, we still didn't have enough points to win. That play changed momentum.
But, I most certainly did not expect our defensive line to so totally own their OL for 45 minutes. Not sure what happened in those last 15 minutes, but at least for 3 quarters, it was great.
