2) At game-time, the referees give lip service to the inspection, opting to use their sense of touch/feel vs an actual psi gauge on 12 or more footballs to assess each ball's individual pressure spec (again, this is my guess...and it could also be the reason why the NFL is now "very disappointed" because this check has not been rigorously/uniformly conducted).
3) All Teams know this...and present their footballs "as is" for the inspection, whether overly inflated like the Packers, or slightly underinflated like the Patriots (or maybe several other teams?). The idea here is that it's "on the referees" to determine the suitability of the balls...not the team itself.
4) Both BB and TB are well aware of this phenomenon, just like Aaron Rogers and the Packers are, so I guess you could say that they are all "complicit". However I'm guessing they would never stand in the way of a finding whereby a ball (or balls) needed to be inflated to a higher psi, if so determined. Yet they'd certainly accept the use of the balls "as is" because it's already been determined (in all those previous practices and games) that they are perfectly aligned to the preference of the QB who will be handling and/or throwing them during the game.
