Texas A&M vs. Cal. Late 3rd quarter...
Cal deep in A&M territory, RB jumps over crowd, breaks plane (or did he????) then ball comes loose, defence recovers. Nothing from side guys. Crew gets together. 1 minute goes by. R finally comes out and signals 1D for A&M.
Announcers claim a TD was scored. I bet the guys in the truck had it all cued up, RTG. They show all the replays... yup he broke the plane.
R gets the signal that the replay booth is reviewing the play. R goes over, 30s later comes back to tell everyone that the play was a TD.
If they were using the Canadian mechanic, the U would've signalled TD and there's be no unnecessary interruption in the game.
