On a day full of critical calls and non-calls by officials late in games, the Broncos seemed to get away with one on the Chiefs' failed final fourth down. McGrath was being held by Denver's Duke Ihenacho. And even if it wasn't holding, it was illegal contact because Ihenacho contacted McGrath more than five yards off the ball. It probably should have been first-and-goal at the 8 for Kansas City instead of game over.
