The plays that the Patriots ran were completely legal, albeit unusual. There's nothing wrong with that--the formations were completely within the rules and deception like that should be more common in football, in my opinion. If they intentionally deflated the footballs, however, that is a more serious matter.
I was kidding about the plays, but it does contribute to ‘they cheat’. I posted earlier that it could have been a faulty air gauge.
Now I am thinking the officials just didn’t check them. Probably a ‘gentlemens agreement’ that the teams each provide balls, and the officials let them use what they want. I just don’t see how Kraft/Belichick/Brady/ballboy gets their hands on all the balls and has 2 minutes (10 seconds per ball) to vacate some air...Just can’t happen like that...
