Odds & ends: Will pattern continue?

BOSTON -- Our friends at Elias Sports Bureau add a few more noteworthy nuggets as we wait for Game 7 between the Boston Celtics and Philadelphia 76ers at TD Garden:

* The Celtics and Sixers have alternated wins through the first six games of this series, with Boston winning Games 1, 3 and 5 and Philadelphia coming out on top in Games 2, 4 and 6. Since the NBA instituted the current playoff format in 1983, there have been 60 series that have gone a full seven games. In only two of those series did the opposing teams alternate wins in all seven games: Seattle vs. Phoenix in 1993 (conference finals) and Phoenix vs. the Clippers in 2006 (conference semifinals).

* Doc Rivers has lost two Game 7s at home in his career as a head coach (2005 against the Pacers and 2009 against the Magic). Only one other head coach in NBA history has suffered multiple Game 7 losses at home in his career: Pat Riley (2).

* This is the first time Doug Collins will be appearing in a Game 7 in his career as a head coach. Prior to tonight's Game 7, Collins’ 55 playoff games were by far the most of any head coach in NBA history who had never appeared in a Game 7. That distinction now belongs to Bob Hill (37).
