Here's the bottom line for the umpteenth time:
Bad call, we obviously got a break. But bad calls happen all the time in NFL games, there will be some on Sunday. That's the human element to officiating (See face mask; Goff). If this PI play happened in the first quarter, no one would care even though it potentially could have cost the Saints points and had just as big an impact on the final score. That's called recency bias.
Saints are whiny bitches. They and the media in their back pockets (see Esiason, Boomer) want to isolate that singular play in a vacuum. Nothing that transpired after it should have happened in their view and but the real kicker is, nothing that happened before that play (see facemask, Goff) matters either.
Doesn't work that way. So f off Saints.
