Barely got it down with the zebras on their side.
What was Big Bens QB rating... 44?
Here's the reality of why Seattle lost the game, again, which I'm sure you'll ignore, again:
Seattles first 3 possession went into Steeler territory, but two were stopped beyond FG range so they only got points on 1. Get another 1st down (note Seattle's terrible 5 for 17 3rd conversion rate) and get into FG range that's 6 points they get.
On two consecutive plays Seattle receivers caught almost garaunteed TDs out of bounds. There's another 7 points they missed.
I won't count the missed FG after the blown TD because had they caught the ball there'd have been no FG kick.
But then on the final possession of the 1st half they once again fell one converted 3rd down short of good FG range and missed it, there's another 3 points they missed.
