I'm guessing that Brady comes clean, saying that he asked for a little air to come out of the balls. His reasoned defense will be that he has been in this league for a long time, has talked to a lot of QBs and they all talked amongst themselves about what they do to the ball to get it to their preferential game ready state. Why is getting the ball sticky with coke, or scruffing it up any different than adding or subtracting a little air? He may even say that he had no idea that what he was doing was against any rules. And lastly he may ask why the NFL allows each side their own set of balls. The implication, of course, would be so that they could each "prep" them to their handling satisfaction.
What's anybody gonna say to that when there have already been several past or present NFL QBs who have already stated that they routinely did something similar ?
The truth shall set you free.
