PHILADELPHIA (AP) — The Philadelphia 76ers fired coach Doc Rivers following a third straight exit in the second round of the playoffs. It was the second time in that span that he lost a series lead and a Game 7. Rivers led the 76ers to their second straight 50-win season behind NBA MVP Joel Embiid but again failed to lead them to the Eastern Conference Finals or beyond. The 76ers held a 3-2 semifinal series lead against Boston before dropping Game 6 at home and were crushed in Game 7 on the road. Rivers fell to 6-10 in Game 7s. He had two years left on his contract. He won the 2008 NBA title as coach of the Boston Celtics.
