They were up 13-10 when they did it. They didn't do a good job showing it but it looked like more of a read play....the old "water bucket" on extra points.
Basically you line everyone up on one side with the exception of center, holder, and kicker. If they think its "there", the center "snaps" it to a guy behind all those lineman....he doesn't have to snap between his legs, so its more of a throw. Can result in an easy 2 points but if it doesn't work, you look like idiots. ha ha.
ECU corner played it perfect and forced the guy back inside. Its not used much anymore for obvious reasons. Even when it was used (we used it in high school way back when)....we never ran it. We always shifted into PAT.
Its just a wrinkle that has a few options off of it but is almost never used. They tried it and still almost got in.
