So if I am understanding this correctly (and please forgive me if I am stating the obvious), for the Patriots to have done something wrong, Tom Brady would have had to instruct an equipment manager to sneak the footballs into the bathroom after they'd been approved by the officials to then reduce the PSI in each football by about 1 to 2 PSI.
The statement above is based on the assumption that the Pats can deliver footballs to the officials that are not in compliance with PSI requirements and it is up to the officials to finalize the acceptance of the footballs. Further assumption is that if the officials were to approve a football that is out of compliance, it is the official, not the Patriots, who would be responsible.
It would not surprise me at all if Tom and the Pats deliver footballs to the officials that are below the required PSI. In fact, if the point is that the teams have discretion regarding getting the footballs the way they want them, I would be surprised if the Pats, or any team, are focused on PSI as opposed to simply trying to get the footballs to match their quarterback's preferences.
It would surprise me a lot if Tom (and I am assuming it could be no one other than Tom) would surrupticiously conspire with an equipment manager to do something so obviously against the rules -- and something that could so easily be detected or determined -- either by someone catching him in that act, or via an investigation. If Brady did this, he should be severely reprimanded -- not only for the wrongness of it, but for manipulating an equipment manager to act on his request. I do not believe it happened.
This has been a disgusting display of piling onto a rumor and I am jacked and pumped for this game even more than before.
