"Note that murder scores relatively high, but the raw numbers are extremely low (there are two in the database, though a third case — domestic in nature — resulted in suicide). But there are 83 domestic violence arrests, making it by far the NFL’s worst category — with a relative arrest rate of 55.4 percent.
Although this is still lower than the national average, it’s extremely high relative to expectations. That 55.4 percent is more than four times worse than the league’s arrest rate for all offenses (13 percent), and domestic violence accounts for 48 percent of arrests for violent crimes among NFL players, compared to our estimated 21 percent nationally.

Moreover, relative to the income level (top 1 percent) and poverty rate (0 percent) of NFL players, the domestic violence arrest rate is downright extraordinary. According to a 2002 Bureau of Justice Statistics Report covering 1993 to 1998, the domestic victimization rate for women in households with income greater than $75,000 (3.3 per 100,000) was about 39 percent of the overall rate (8.4 per 100,000), and less than 20 percent of the rate for women ages 20 to 34.
