While there is a valid argument over what Hawks' personnel was on the floor for the final possession of Game 3, it was a defensive miscommunication that gave Paul Pierce enough room to make the final shot.
Lost in the hoopla over who was or wasn't in the game and the reasoning for it was an apparent miscommunication by the Hawks defensively on the final possession of Game 3 which led to Paul Pierce's buzzer beater. Kyle Korver began the possession matched up against Pierce, but an ill-timed switch by Dennis Schröder gave Pierce just enough room to bury the game winner and thus bury the Hawks.
