Cleaning out your locker room after an NFL season is nothing new. Once teams are eliminated from contention players will go back to the locker room and clean out their lockers for the year. Since they are probably not going to be back in the building until around April or May.
When you are Tom Brady you happen to have a suite in the stadium of course. Where his wife model Gisele Bundchen and their kids sit and watch the games. This is the area that received heavy cleaning. That is why eyebrows are being raised.
