I don't think there's a coach in CFB or the NFL who tells the player to stop at the 1 with plans on getting the TD a little later. FSU has two timeouts. They call the first one when he takes the knee. If Auburn scores on the next play, they succeeded in forcing FSU to use a TO. If they get stuffed, or take another knee(insanity), FSU burns their second TO. 2nd down. AU has burnt 10 seconds and forced FSU to use their TO. If they get stuffed, or take another knee(insanity part 2), they can actually run out the clock because it's now 3rd down with 50+ seconds left. So, really, very little is gained if AU scores on 1st/2nd down because the clock stops on 1st downs and clocking the ball isn't a big deal because you're already in 4 down territory if you're FSU.
If I can think this out, do you not think a coach playing for the Natty hasn't already played it out?
