The entire incident began when the Colts intercepted a ball in the first half of the AFC championship game and found it to have low pressure. After the Colts informed the league, all 11 of the Patriots’ balls were inspected and found to be below the allowable level. Patriots sources are steadfast—and their belief was conveyed to the league, according to a source—that Mike Kensil, the NFL’s VP of game operations, walked up to Patriots equipment manager Dave Schoenfeld on the sideline after halftime and said, “We weighed the balls. You are in big f------ trouble.” New England and Kraft thought this incident, and others, showed bias by the league and would be explored in the Wells report. But the
Patriots’ theories (including another in which they believed the Colts deflated the intercepted ball) were tossed aside, with the report simply calling the sideline interaction a difference in recollection.
“I really don’t see how Robert is going to get past this with Roger,” says a source close to Kraft. “Robert was furious with the leaks and the investigation in the first place, but he figured they’d be exonerated. Now he’s out of his mind with anger.”
