Philadelphia 76ers head coach Doc Rivers slammed his side for playing "hero basketball" as the Eastern Conference top seeds surrendered their lead against the Atlanta Hawks in the semi-finals.
The 76ers squandered a 13-point advantage in Atlanta, where the Hawks rallied to a 103-100 victory in Game 4 in the NBA playoffs on Monday.
Atlanta levelled the second-round matchup at 2-2 after 76ers All-Star and MVP finalist Joel Embiid missed an open lay-up in the dying stages, before Seth Curry's unsuccessful buzzer-beating three-point attempt to force overtime.
The 76ers saw their lead whittled away as the Hawks overpowered the visitors, irritating Rivers post-game.
"We stopped passing. I thought we started the game off that way," Rivers told reporters. "Then we got back into the ball movement and went back to hero basketball. Basically everybody wanted to be the hero instead of trusting the team, trusting each other.
"When you do that you usually lose especially when the other team outworks you the whole f****** game and that's what they did today."
Embiid, who has been battling knee issues during the playoffs, finished with 17 points and a playoff career-high 21 rebounds, yet appeared hampered.
Philadelphia's Embiid sustained a small meniscus tear in Game 4 of the first-round series against the Washington Wizards, returning for the semi-final opener with the fifth-seeded Hawks.
Rivers was unable to provide an update on Embiid's injury status.
"I don't know. He went in the back [to the locker room]," Rivers said. "I know something was bothering him but I'm not sure what it was."
Rivers refused to criticise Embiid for his late miss at 101-100, nor his side's final play for Curry's tough shot on the buzzer.
"To me the game should never have come to that point," Rivers said. "We missed so many opportunities. My eyes told me we blew a golden opportunity tonight."
On the final play, Rivers added: "It's seven seconds, you've got to go the length of the floor.
"That's what we drew up but anybody could have been open. We got a decent shot, Seth had a decent look, thought he'd made it."
Rivers felt the Hawks were the "more physical and tougher team".
The two sides meet again in Game 5 in Philadelphia on Wednesday.
