Why should,it be a fine and a pick when they warned,the Vikings and Panthers? And if the answer is to,protect Goodell then the Krafts should fight it with everything they have. The NFL f.cked up, the refs never checked the balls and short of true documentation that they used a gauge on each ball and logged the results the patriots should tell them they will not accept punishment without proof. People can say what they want about the league's ability to sanction at will but that doesn't mean they can do so without actual proof of wrongdoing, and in this case they have none. Imo the Patriots inflated the balls to 12.5 per requirement and the refs simply squeeze tested a few and said they were good, then when they pulled them they were under because of the weather. No harm, no foul. Case closed, come up with a better protocol.
I don't believe anyone tampered with them and the Krafts should come out and tell the world that they will challenge future claims that someone did in court.
