Tempo Free Stats in Basketball

With the start of Basketball season and Danny's new interest in the Bucks, I thought I would post a little about tempo-free statistics for basketball.
Like defense-adjusted statistics in baseball, tempo-free statistics in basketball try to eliminate some of the variables in basketball statistics in order to more accurately compare the performance of players and teams.

The fundamental adjustment of tempo-free stats is that the statistics are reported on a basis of per 100 possessions, rather than per game or per minute. This provides an analysis of how efficient a player or team is in either scoring or defending on each possession. Some games will be played at a higher tempo, thus resulting in a greater number of possessions while other games have a slower pace, resulting in fewer possessions. Tempo-free stats try to adjust for these differences.

The guys over at Cracked Sidewalks have posted a pretty good primer here and here on tempo-free stats for basketball analysis.

For NBA analysis, www.82games.com and www.basketballprospectus.com provide tempo-free statistics and analysis.

Interesting. I'm always skeptical when someone tries to create Moneyball-style statistics for other sports than baseball, but this has some promise.

Rate stats are always better than counting stats for just the reason you cite. Nice work.
