So, here's something else about the blown call that got me thinking (although not related to bad officiating)
Say they did make the correct call and call PI. Saints have the ball 1st and goal at the 5 with about 1:45 left. LA has 1 timeout. If you're Sean Payton, how do you play that?
I would've taken 3 knees (assuming LA uses their TO), using one of them to center the ball, run the clock down to 5 seconds and then tried a ~23 yd FG on the last play. FG under 30 yards at least ~95% successful. And if he misses, it's OT, where you're 50-50. So that strategy gives you like a 98% chance to win
But, I feel like a lot of people would've tried for a TD. But if you score too early, LA gets a shot to tie. Or worse, you throw an incomplete pass or 2, settle for a FG, and the Rams have time to tie or win with a TD. You're still likely wo win, but not as much as 3 knees, IMO.
