According to @wojespn, Philadelphia’s Jimmy Butler has aggressively challenged coach Brett Brown on All-Star’s role in 76ers offense.

Butler is further complicating an already-tenuous chemistry among team’s Big 3 hierarchy.

Butler has been vocal in his contesting of Brown and his system, including a recent film session in Portland that some witnesses considered “disrespectful” and beyond normal player-coach discourse.

Brown has told people within the organization that he had no issues with that exchange and considered it within the confines of the relationship that he’s developed with Butler, sources said.
