For the first time since July 2009, the NFL went a calendar month without a single arrest, according to Mike Rosenberg of Reuters, based on information from USA Today and the San Diego Union-Tribune. It's also the first time in 15 years the NFL went without an arrest for an entire month during the season, per Rosenberg.
On Oct. 8, commissioner Roger Goodell highlighted how much the league's number of arrests had shrunk in 2015, according to Ian Rapoport of NFL Network:
It's good news for the NFL, which underwent one of its most controversial years in its history in 2014, including high-profile situations such as the Ray Rice assault case and Adrian Peterson's arrest for child abuse.
It is worth noting the NFL's arrest rate was actually two times lower than that of men aged 20-39 from 2000-2013, according to a study by University of Texas-Dallas criminologists, per Yahoo SportsDash. But the league will undoubtedly be pleased it was able to go an entire month without having to deal with the negative publicity associated with one of its players being arrested.
