Video: Andy Reid Dresses as Santa Claus in Chiefs' Locker Room After Win vs. Steelers

The Kansas City Chiefs felt jolly after a 29-10 win over the Pittsburgh Steelers.

Head coach Andy Reid dressed up as Santa Claus in the locker room to deliver a special message to his team.

"For the present, you get home-field advantage," he said.

Chiefs stars Patrick Mahomes and Travis Kelce also donned some festive gear after taking home the win:

The Chiefs improved to 15-1 and clinched the top seed in the AFC with the win, giving them a first-round bye and home-field advantage throughout the playoffs. Mahomes threw for 320 yards and three touchdowns in the game and Kelce was his favorite target as he reeled in eight receptions for 84 yards and a touchdown.

Kelce's touchdown was the 77th of his career, giving him Kansas City's record for the most receiving touchdowns. The historic mark previously belonged to Hall of Fame tight end Tony Gonzalez.

Despite facing one of the best teams in the AFC, Kansas City put together one of its most dominant performances of the year. It was just the fourth time this season the Chiefs have won by double-digits and just the third time Mahomes has thrown for 300 or more yards, a positive sign as the playoffs near.

The win gives Kansas City its sixth in a row following a Week 11 loss to the Buffalo Bills.

The Chiefs now have their first-ever season with 15 or more wins, and they're one win away from finishing with just one loss for the first time in franchise history.

Kansas City will take on the Denver Broncos to close out the season next week. After that, the Chiefs will look to follow up their historic year with a third straight Super Bowl victory.
