Not buying it. It was 50 at game time and I’ve read that all balls are checked at the same time and marked. If it were so easy for 11 of 12 balls to fall under spec on what could be considered almost a fall-like day for football, then:

A. There’d be no psi rule to begin with because it would be too difficult to enforce.

B. This would be a very common occurrence and there would be no split among former players and other experts.

...and dropping. But if a ball is cooled from 75 to 50, that’s more than enough to drop pressure from out of spec overfilled, to out of spec under filled.

There’s reason to believe it is not generally enforced with much dilligence.

B. This would be a very common occurrence and there would be no split among former players and other experts.

It’d only be common if anyone regularly checked. Rogers, for example, implies he gets enough of the over-inflated balls he stated he submits through to get through games using them.

From ESPN reporting of a Goodell press conference Jan 30
“No knowledge of past in-game testing.
Asked if the NFL has tested the air pressure in footballs during a game in the past, and how important that is as a frame of reference in the ongoing investigation, Goodell said he didn’t know the answer and that attorney Ted Wells will look into that as part of the investigation. From our viewpoint, this answer warrants scrutiny based on the magnitude of the NFL’s investigation and the media firestorm it has created. How could Goodell not know? “

You don’t know of previous examples because no one checked before.
