It just doesn’t get much better than this. A matchup of two franchises with a well-established rivalry, from the days of Wilt Chamberlain and Bill Russell to Julius Erving and Larry Bird, the 76ers and Celtics go way back. As of late, the Celtics have dominated the Sixers, especially since Kevin Garnett and Ray Allen arrived in Boston, but this year, it appears Philadelphia may be competitive again. The 76ers have taken two of three in the season series this year against the Celtics, with both wins coming in blowouts. In all fairness to Boston, the first loss was after two straight overtime games and both were on the second night of a back-to-back. The Celtics struggled with Atlanta’s athleticism in the first round, but in the end, Boston’s playoff experience simply wore down the Hawks. Almost no one expected the 76ers to be in this position at the beginning of the playoffs, but after Andre Iguodala’s clutch free throws with 2.2 seconds remaining to send Chicago home, Philly looks to continue its improbable run.
