Even with Belichick not calling a timeout the Seahawks would still have been able to get off three plays, most likely even three rushes if they hadn't decided to let the clock run down. While handing off to Lynch should be their preferred option Wilson is capable of throwing a TD pass in that situation as well.
The stats regarding a situation like that support the theory that Belichick got extremely lucky. During the 2014 season two of 318 plays (0.6%) from the 1-yard line resulted in a turnover, none of them an interception. The last time the Seahawks turned the ball over from the 1 before that play happened during the 2004 season.
I'm with TJV that it's ridiculous to call Belichick not taking a timeout the best call in Super Bowl history.
While it's hard to say if Belichick's call was the best in Super Bowl history, there was logic behind it.
On 2nd. down, Belichick had two choice:
(1) Call timeout as Seattle huddled up to run the clock down, as one would expect them to, or
(2) Let the clock run and play to stop them.
Had he opted for (1), he would be assuming Seattle is going to score. If that was the assumption, then the smart thing to do would be to
let them score on 2nd. down, get the ball back with 1:00 left on the clock and 1 timeout in order to play for the FG and OT.
Instead, Belichick chose (2).
While the wisdom of choosing option (2) can always be debated, once the choice was made, not calling the timeout was the smart thing to do.
There's one "second guess" that has not been explored. What if Seattle had chosen to snap the ball on second down with 0:35 on the clock instead of running it down to 0:26? Had they scored on 2nd. down they'd be giving Brady the ball with something less than 0:25 assuming some sort of pooch kick.
Whether Seattle could have run the ball 3 times in 0:26 with one timeout is debatable, but the fact that Carrol evidently believed it to be a tight squeeze, or was not comfortable trying to pull it off with one no huddle snap, led him to the 2nd. down throw.
The parallels to the 1998 Super Bowl are interesting. In a tie game with 1:48 on the clock, Holmgren opted to let Davis run the ball in from the 1 yard line. He later admitted it was a mistake in that he thought it was first down, not second down, and that Denver could have run the clock down to 0:25 if Holmgren was to conserve his timeouts:

I think it's fair to say Belichick knew it was second down, chose option (2), and acted consistently with that choice.
