You don’t want PI’s reviewed. Yeah, last night was obvious but many of them aren’t and if you start opening them to review you are going to have the booth overturn an iffy one and piss off a fanbase as bad as the Saints are today.
Besides any of that, after the PI the Saints allowed the Rams to get in FG position and tie it. Then the Saints win the toss in OT, turn it over, and then allow the Rams to move into game winning FG position.
It was a missed call, no doubt. But I can’t pin 65 minutes of football on that one call.
