It may be unwise to make the Cleveland Browns the butt of your joke now that they have brought in "The Iceman" to their training camp.

UFC Hall of Famer Chuck Liddell was invited to Browns camp to teach them some fighting techniques as the Browns prepare for the upcoming season. More specifically, the focus was on body-to-body contact and manipulation which will come in handy during the game.

Liddell also said he worked with the team—which has gone 1-31 over the last two seasons—on changing its mindset, "It's a fight. This is not just a game. We're fighting to win."

The former light heavyweight champion of the world also had players punching and kneeing bags, though that may be more suited for the Dawg Pound than on the gridiron.

The Browns will need that mean streak in a competitive and physical AFC North when the 2018 season gets underway.
