Anyone catch Carroll's explanation on the play call?
He was going to call 1 pass play, then run on 3rd, call timeout (at .01), then run on 4th.
That gives the Seahawks 3 shots at the endzone, and eats up the maximum amount of clock since they can call timeout with 1 second after 3rd down.
Contrasted with running the ball on 2nd down. If he doesn't get it, they have to call timeout. And then you have to pass the ball on 3rd, and can't control the clock and a sack probably ends the game. Then you run the ball on 4th, and leave time on the clock for Pats who only need a fg.
In the end, they were calling 2 runs and 1 pass. This was just the smart way to do it. (I certainly didn't think so at the time. But then he explained it, and I was "ohhhhhhhhhhhhhhh."
