Whoa -- stop the presses. In my WNBA-NBA comparison numbers below, I originally used turnover numbers for the NBA from ESPN.com and CNNSI.com. Those turnover numbers are just the sums of the individual players' numbers, which means they exclude turnovers attributed to the team (shot clock violations).

Thus, my originaly data understated NBA turnovers by about 5%. The NBA assist-turnover ratio is 1.42, not 1.50. All of the numbers below have been updated now.

The disparity between the WNBA and the NBA is substantial, but not as large as I said yesterday. The turnover-per-minute difference is 17%, not 23%.
