“‘I’m proud of you, boy, you’re going to my team. You’re going to my favorite team, the Boston Celtics, man,’” Williams recalled in his old man voice that he insists sounds just like his grandfather. [....] Williams’ younger brother became a Patriots fan and his oldest is a Bruins fan. For some reason, his family from Charlotte had always just naturally gravitated toward Boston teams.
“[Grant's grandfather] was just talking about how much he would love it if I end up playing for Boston, because he would always come visit me,” Williams told The Athletic. “The fact that it actually happened and to see his face, that was one of the best things that happened last night.”
Landing with one of the two teams on his preferred list was not just a thrill for his family, but he also sees it as a key for his potential to maximize his career. Williams said he loves Al Horford and spent the last two years studying how the Celtics used him in their offense, something he will try to emulate as a short rolling screener or midrange shot creator.
