I have no idea what that is but I would like to know. The league should want to know too. We should not just overlook it because it is Tom Brady. We don't need a public investigation but someone from the league office should make the trip to Tampa to ask Brady. If it's nothing then that's the end of it.
I know a lot of pitchers in baseball, as they got older, resorted to bending the rules to extend their careers. Scuffing the ball or slipping some kind of liquid on it was not unheard of, even by some pitchers in the hall of fame.
