Bill Belichick said on Friday that the kicking balls used in the first half of the New England Patriots' matchup against the Kansas City Chiefs Sunday were "underinflated by 2, 2½ pounds."
Per ESPN's Mike Reiss, he knew they were underinflated, but he doesn't know why. The veteran coach is awaiting an explanation from the NFL after the 27-17 loss.
"We don't have anything to do with it. Were we aware of it? Yeah, definitely," Belichick said. "As I understand it, they were all the same. I don't know what the explanation is. It was the same for both teams.
