Philadelphia 76ers coach Brett Brown admittedly has no idea when All-Stars Joel Embiid and Ben Simmons will return from their respective injuries. Brown expressed more clairvoyance, however, on how their NBA careers will turn out. “I personally am convinced those two are going to win a championship at some point in their career and that they, for sure, can coexist,” Brown said following practice Monday at UCLA. “The myth is that they can’t. I think that is so abused and not articulated the way I see it.”
