Just to play devils advocate since everyone is so intent on piling on Brady.
Everyone has to make everything so sinister. Could have been fairly innocent, and everyone is saying that the equipment manager is being thrown under the bus, but maybe it really is his fault? Hear me out.
All the QB's that commented today confirmed that what Brady said was true, before each game the QB's go in and pick out the balls they like the best, and do little things to them to make them more comfortable to throw WHICH CAN INCLUDE adding or letting out some air. That's legal and everyone does it as long as its in that legal PSI range.
So isn't it possible that in this process, Tom picked out his balls (hehe) and told the equipment manager, these are good but they feel a little over inflated, can you take them right down to 12.5 (which is the legal limit and where Brady said he likes them.)
So maybe Brady did tell him to let some air out but he didn't necessarily say hey take 2 pounds out, I'm gonna cheat, #YOLO
I'm just saying, it's possible they all cheated and are super evil villans and should be killed like all the indignant media is making out, but it is just as likely that it was an honest mistake by an overzealous equipment manager eager to please his superstar QB.
