Grant Williams was traded to the Dallas Mavericks from the Boston Celtics in the offseason.
There's one person in the Metroplex who seems to despite that deal: Dak Prescott's older brother Tad.
Following the Mavs' win against the Charlotte Hornets on Sunday, Williams showed up to the postgame press conference wearing a Philadelphia Eagles jersey, notable one of star center Jason Kelce.
Tad Prescott did not take too kindly to the gesture, and called out Williams on X.
Williams kindly responded to the attack, accompanying his response with a picture of Cowboys linebacker Micah Parsons attending a Mavs game, wearing a Philadelphia 76ers jersey!
Tad Prescott isn't the only person Williams has angered: Obviously Cowboys fans have something to say about the Mavs forward wearing an Eagles jersey.
