BOSTON (AP) — The Celtics finally found cohesion between their defense and offense in their Game 4 win, capitalizing off 16 Heat turnovers and finding their 3-point shot. Now down 3-1, the question is whether Boston can carry that energy home, a place where it is just 4-5 this postseason to keep alive its hopes of extending the series. At the very least the Celtics’ win made their hopes of becoming the first NBA team in 151 tries to overcome a 3-0 deficit in a best-of-seven series shift from insurmountable back to possible heading into Game 5.
