Having said all that, I'd still like to know the answer to my hypothetical. If the Jets kicks a FG on the opening possession of OT, then Peyton throws an INT on the ensuing possession. Is the play whistled dead/game over at the instant the Jets player establishes complete control of the ball, or is the play live until he's tackled, or runs out of bounds, or downs himself?
And if the refs let the play resolve itself, and the Jets player is stripped and the Colts recover it, do they HAVE to score on that same play, with some wacky lateral-fest, to win the game? One would think so, since the Colts will have had their possession, but I'm just curious.
