A "Walk Off Touchdown" ??

[mike340]

I don't think this is a "walk-off" TD. Why?
How often do you hear about a walk-off single. Almost never. But a walk-off homer, absolutely. I believe the reason for this is that the runner in a game-ending single cannot take his leisure in his part in the game until the game is over. But for a walk-off homer, the batter can take all the time he likes before the game is finished (think of the time Barry Bonds takes adoring his home runs.) So I think the following criteria are necessary for an event to be considered "walk-off".
1) The event must put one of the teams ahead when it wasn't before. (No walk-off double plays.)
2) The action causing the event must be performed by the team that goes into the lead. (I don't believe in walk-off balks.)
3) The other team has no way to retake the lead by the rules of the game.
4) There is some other action to be completed before the end of the game which is necessary by the rules to win the game. Furthermore, this action can be performed by the athlete at his leisure (i.e. he can walk when accomplishing this action.) (no walk-off singles.)

I could try to be more technical, but I think it would be pointless. Note that, by this definition, in baseball one can have a walk-off home run and a walk-off ground rule double.

Sorry to belabor the point, but this expression (walk-off TD) just bothers me.
(Of course, I'm making a mountain out of a molehill.)
