“I had a relationship with Charles before, because we went to Basketball Without Borders two years prior, so I’d known him from that,” Grant Williams said on Friday. “So when he got the job, I texted him immediately. I was like … we always talked about you coaching me, and I thought it was gonna be in Milwaukee, and that you would go to Boston, and I thought I was gonna be in Boston, and I’m not in Boston anymore, and now it’s in Charlotte. “It’s really cool to have him here. The first thing we talked about is just getting guys together … we had a group chat with Melo, myself and everybody else trying to just communicate … (Lee) did his actual job being with the Celtics, but also checking in on us, making sure we’re doing our thing, making sure we’re prepared for this upcoming year and giving tidbits on what he wants and expects.”
