Tristan Thompson is back in the headlines, and this time it's not about his love life drama or his basketball prowess. No, this time around, the NBA vet is making a serious and deeply personal legal move that's turning heads for very different reasons. According to newly surfaced court documents first obtained and reported on by TMZ on Tuesday, Tristan is seeking to step up his role in a major way when it comes to his younger brother, Amari Thompson. That's right: in the docs, the athlete has reportedly filed to place Amari, who is disabled, under a conservatorship.
