Flagg, the player coming to Dallas to save the Mavericks from last year’s disaster, is not a finished product.

During a recent NBA Summer League game, the former Duke standouts greeted each other courtside before tipoff, sharing a quick handshake and smile. The wholesome exchange didn’t go unnoticed, especially by Flagg’s mom, Kelly, who responded to the clip on social media with a heartfelt message: “Brothers forever.”
