Over the weekend, we heard more on the record from Mavericks assistant general manager Michael Finley describing one noteworthy exchange between Williams and Mavericks star Luka Doncic. “I remember, just to share a quick story with you guys,” Finley said. “One day in practice, a player on our team, I won’t call his name out — but it’s Grant Williams. He decided he wanted to get under Luka’s skin. He felt Luka didn’t come that day ready to practice. To make a long story short, they had a scrimmage going and he was talking trash to Luka up and down the court. So finally, Luka says ‘Okay,” and Luka went on a 26-6 run by himself. You can ask anybody, I’m not exaggerating. He showed everything, the 3s, the postups, the floaters, everything by himself.”
