I was watching the Ravens/Chargers game, and joked to my Ravens fan friend "hey, the Ravens should do an onside kick to start the OT. No one would ever suspect it."
Does a team actually have to possess the ball in OT, or just have the opportunity to do so?
For example, suppose the Ravens had used the onside kick to open the OT, and recovered. Then a few plays later they kick the FG. Is the game over?
Or, suppose the Chargers had received the opening kick for the OT, driven into FG range, and then kicked the FG. If they try an onside kick and recover it, is the game over? Or do they just get a second chance to score again???
