‘Belicheat’ emerged from the shadows for the second time after the AFC Championship game in 2015. The Indianapolis Colts alleged that Tom Brady used underinflated balls to gain a tactical advantage. Most people agree that there’s no way Belichick didn’t know about it. However, he shrugged and compared himself to the Mona Lisa (via Time).
