Euphoria

That is correct!
The head of the officials confirmed this during the week in an interview. And even explained it this way:

If say team A takes the OT kick off and scores field goal. Then kicks an onside kick and recovers the ball the game is over. Because team B did have an oppitunity to posses the ball.

They both agreed that they would not know why ANYONE would even attempt an onside kick in that situation.

But I guess they already for got last year's SB.
