Bruschi brought up something I have said for a while. Why would Brady have a ball boy go into a bathroom and quickly deflate 12 balls without gauging them (and there is no way McNally could have deflate the balls and gauge them). By doing that, he risks getting too underinflated balls. It would be better to risk that the refs kept them at 12.5 PSI.
And take them out of a bag, line up and take air out of a dozen balls, put them back in the bag in 90 sec.
How much do they think is not explained by temperature? Would Brady really risk all this coming down for a small fraction of a PSI?
