Video: Mariah Carey Performs 'All I Want for Christmas Is You' Before Chiefs-Steelers

Netflix kicked off its first-ever Christmas Day broadcast of the NFL with a full "All I Want for Christmas Is You" performance from Mariah Carey.

Netflix is broadcasting a pair of games on Christmas—the Kansas City Chiefs facing the Pittsburgh Steelers, and the Baltimore Ravens taking on the Houston Texans.

Both games have major playoff implications. A win would clinch the top seed in the AFC playoffs for the 14-1 Chiefs, while the Steelers and Ravens are both 10-5 and gunning for the AFC North title.

And a Steelers loss and Texans win would propel Houston to the No. 3 seed in the postseason. So with respect to Carey's original lyrics, all the Chiefs, Steelers, Ravens and Texans want for Christmas is a win.
