Halfway through the second quarter of game 5 against the Hawks, the Celtics took the lead. That advantage went from two points to 13 just a couple of minutes into the third quarter.
With a minute and a half left in the game, Atlanta came all the way back and led 114-113, overcoming the 13-point deficit just seven minutes prior. When the game clock hit zero, the DeJounte Murray-less Hawks had won 119-117.
The collapse by the Celtics was their worst of the postseason so far and allowed the No. 7 seed Hawks to avoid elimination for at least another game and make the series 3-2.
