When that Saint made a ridiculous circus catch right before the 2 minute warning to extend the drive and put the Saints on first down from the Rams 13 in a tied game, I told my daughter "if the game is fixed, that play wasnt supposed to happen but they can't prevent athletes not in on it from making miracle plays so look for them to find a way to bail out the Rams by either having the Saints make some really bizarrely stupid decisions or the officials to make some terrible calls that help the Rams. Let's see if it's fixed". First step was to find a way to preserve the clock because the Rams wasted a time out stupidly and couldn't do it themselves.
So of course Payton mysteriously chose to throw the ball on first down, incomplete and stopped the clock. Then he called a really short pass, then you got the horrible pass interference, clock stops again. Saints basically took a field goal but took no time off the clock. Rams get ball, a couple of big plays later plus a questionable call or two, field goal for the tie and OT.
I guess I know the answer now.
