But Mahomes wouldn’t have a good time watching his Dallas Mavericks lose 117-95 to the Oklahoma City Thunder in Game 1 of the second-round NBA playoffs

A native of Tyler, Texas, the three-time Super Bowl champion Mahomes is a part-owner of the Kansas City Royals, MLS’s Sporting Kansas City, and NWSL’s Kansas City Current.

So the three-time MVP isn’t afraid to post on social media about his fandom for his favorite sports teams.

With the NBA playoffs in full swing, the Chiefs superstar signal-caller decided to post on social media about the Mavericks.

The No. 5 seed went on the road to take on the No. 1 seed Thunder.

Before the tip-off, Mahomes wrote on X, formerly known as Twitter, , “Let’s get it! @dallasmavs.”

The Mavericks couldn’t win the game for the three-time Super Bowl MVP.

Dallas ended up losing 117-95 to Oklahoma City.
