Reminds me of a recent playoff game I was R in.
#3 was leading over #2 28-14 with 1:41 to go in the game, and #2 had no timeouts left. 1st and 10 for #3 around mid-field, clock to restart on the ready. #3 captain advises me that they're going to kneel it out.
#3 snaps the ball with about 1:20 on the clock and downs it, 2nd and 12. #3 snaps again, and makes an absolute mess of the snap, and #2 recover the loose ball with 0:37 on the clock. Next play, #2 put a long pass into the end zone, and it's now a 28-21 game.
Onside kick, recovered by #2 (clear recovery, no doubt and no contest). 1st and 10 for #2, from mid-field, 0:35 on the clock. A few good plays (and their last timeout) get them 1st and 10 on the B's 20, clock stopped for the timeout at 0:04. Pass into the endzone, but #3s pass rusher takes 3 steps after the QB releases and nails the QB. I have my flag on the ground for RTP, and glance up to see BJ and FJ signalling incomplete pass, and the clock showing 0:00.
One untimed play from B's 10. Again, pass goes into the end zone, comes off hands, and hits the ground.
So, wasn't an upset in the end, but in 25 years, I've never seen a team that was going to kneel it out for the win suddenly find themselves under that much pressure in the end.
