The Dallas Mavericks and rookie Cooper Flagg dropped their first game after parting ways with general manager Nico Harrison, falling to the Phoenix Suns 123–114 at home on Wednesday.

At some point between last night and this afternoon, when the Mavericks dismissed much-maligned general manager Nico Harrison, Cooper Flagg's mom reposted a fan's post on social media bashing the team's then-GM and calling for his removal.

Cooper Flagg ’s mother, Kelly Flagg, recently stirred up attention with her social media activity. The situation began during the Dallas Mavericks game against the Milwaukee Bucks. Fans in the crowd at the American Airlines Centre expressed their frustration with Nico Harrison for trading Luka Doncic in February 2025.

NBACentel, a popular parody account on the social media platform X, struck again with a fake report about Harrison trying to trade Cooper Flagg before he was fired. The fake report generated over one million views within 24 hours of being posted.

It took longer than it probably should have, but the Mavericks finally decided to kick Nico Harrison to the curb after the GM who orchestrated the trade

The loss dropped Cooper Flagg and the Mavs to 3-9. It was also their second loss in a row, as they started their four-game homestand with a 116-114 defeat to Giannis Antetokounmpo and the Milwaukee Bucks on Monday.

The Dallas Mavericks entered this year hoping to hold steady in the Western Conference playoff race until Kyrie Irving returns, at which point they could fully take off into a legitimate contender.
