The Boston Celtics and Philadelphia 76ers each have two wins going into tonight’s Eastern Conference semifinal Game 5, so the ball is, literally, in either team’s court. During the Western Conference semifinal game that follows at 9:30 p.m. ET, the Los Angeles Lakers are in a more precarious position. Their opponent, the Oklahoma City Thunder, are leading the series 3-1, thanks to a 3-pointer by Kevin Durant just 13.7 seconds before the end of Game 4. There’s so much hoops action one could almost forget that the Stanley Cup playoff Game 4 between the New York Rangers and New Jersey Devils is taking place at 8 p.m. on NBC Sports Network.
