Facing his former team in Cleveland last night, LeBron James played like his vintage Cavs-era self, pouring in 38 points on 15-25 shooting with 8 assists in 30 minutes. That had me wondering, where did James’ performance rank among historical instances of a player facing his ex-’mates the season after he left town?
So I ran a database query on all games since 1987 where a player was facing a team he had played for the previous season. And for the performance metric of choice, I want to introduce an adjusted plus/minus-based game score-style metric called “APMVAL”. I basically ran an intercept-free regression between APM value over replacement (minutes * (APM + 6)) and raw box score totals, coming up with this formula:
APMVAL = 45*pts – 35*tsa + 18*reb + 30*ast + 72*stl + 41*blk – 75*tov – 39*pf
The best APMVAL game of the overall 1987-2010 period was Michael Jordan’s 69-point outburst vs. Cleveland in 1990 (Kobe’s 81-point game was 2nd). Here were the best games against a player’s former team in the first season after his departure:
