Joel Embiid is done for the season, at last shut down following the lingering effects of knee surgery. But plenty of hard questions remain in Philadelphia.

Embiid played just 39 games last season due to a torn meniscus in his left knee. The Sixers announced in early February of that season that he had undergone surgery. He came back in early April, participated in the Sixers' playoff run, and then won a gold medal with the U.S. Olympic team last year at the Paris Games.
