What went wrong in Sixers' disastrous first half vs. Hawks in Game 1?

"I thought they hit us in the mouth to start the game," Doc Rivers said after the game. "I thought they were the more physical team, they were the more aggressive team, they played harder early, and they took care of the ball early. We didn't. You can't have nine turnovers to start the first quarter, and expect to be up."
