Either he's being sarcastic, or he's implying that the Colts will start to become complacent, give easy points away to other teams, and eventually fall into a pit of belief that they don't need to do anything to win the game, simply because it's easy and they're bound to win.

It happens with football teams over here.

In fact, it happened the other day to United.

Top of the Premiership, no-one can catch them, they play a game against Southend - a team only the supporters have heard of... United were thrashed 1-0. They were too sure of themselves.
