There’s a lot of reasons the Cavs have managed to take a 2-1 series lead on the Boston Celtics heading into Sunday afternoon’s Game 4. Plenty of credit is due LeBron James, who is merely averaging 32.3 points and shooting 54 percent in the series. If the Cavs advance to the next round and get a re-match with the Orlando Magic, Parker will probably be dealing with Vince Carter. The Suns beat the Trial Blazers in six games and have a 3-0 lead against the Spurs. With an efficient offense, both in halfcourt and in transition, Phoenix is averaging 117.8 points per 100 possessions, the highest rate in the playoffs, despite a pace that is glacial by Suns standards. The Suns are playing enough defense to make it all stand up.
