Thursday evening’s Sixers-Nets meeting is one of the most anticipated games in South Philly in recent memory, a spectacle with battles within battles within battles. There’s Kevin Durant vs. Joel Embiid, James Harden vs. his former teammates, and Ben Simmons vs. just about everybody. It’s that last piece many are focused on, with league sources anticipating that Simmons and his representation will file a formal grievance against the Sixers at some point in the coming days.
