[Keenum]

Jones peeled off another guy because of the coverage scheme, and if he had peeled off a second too late, that would have been a TD.
I've also heard that since our defense was so worn out and tired (remember, the Titans had a long drive before that, we scored in one play, then another long drive, sparking the famous "You want out of the game with 23 seconds left to go!?" quote) that the Titans would have leaned on going for 2 points and the WIN if they got that TD.
Super heads up play by Jones.
