Sixers-Celtics: Game 7 keys

Philly vs. Boston. Allen vs. Allen. The Truth vs. The Jruth. The old vs. two guys named Young.

OK, maybe this one isn't as easy to build up as some other recent seventh games. It hasn't always been easy on the eyes; you have to be a true defensive purist to appreciate this series, and it helps if you think the 20-foot pick-and-pop jumper is the pinnacle of human achievement.

Big-picture, the contrast between this series and the other three conference semifinals couldn't be more stark. The top three teams in playoff offensive efficiency this spring are Oklahoma City, San Antonio and Miami.
