San Antonio Spurs at Boston Celtics: preview and Win Meter

San Antonio Spurs → Boston Celtics →

San Antonio Spurs at Boston Celtics on Wednesday, March 24 is about as close to a coin flip as the ratings get, with the Celtics at only 55%. Small things like rest, health and shooting variance should decide it.

Why it is so close

The Win Meter reads the Celtics 55%, with a projected score of San Antonio Spurs 114, Boston Celtics 115. The rating gap is 68 points in favor of the Spurs, and home court and rest add about 100 rating points for the Celtics on top of that.
