This thread is really silly and I agree that the conclusions it is attempting to draw are founded on stereotypes. It took me 20 seconds of looking at Terry's Instagram to figure out that GMB is a rap group/label that his friend is trying to start. It appears all of Terry's crew has been marketing GMB to support their friend's musical ambitions. The recent social media name change makes sense from a marketing standpoint as Terry's friend appears ready to drop an album soon. On this gentleman's Instagram, he can be regularly seen with other Celtics and at Celtic facilities. In recent photos, he's on a private jet with Rozier and Crowder, and at IT's wedding taking pictures with Amir and Jae. In an older video, he's in the Waltham practice facility shooting some of Terry's drills. In an older photo, Terry, Evan Turner, Jordan Mickey and David Lee can be seen visiting him at his studio in Boston, where I'd assume he makes his music. I think Danny and Brad are already familiar with this guy, so hold your letters and concerned phone calls to the Cs PR staff.
As for the other stuff, he had a tough upbringing and looked up to people who had money and power. It doesn't mean he's a bad kid for showing where he's from and what he was born out of. It also certainly doesn't mean he's involved in their current or past activities.
