Richie Incognito gets a job after bullying report. Has the NFL learned?

After being excoriated in The Wells Report, which revealed homophobic bullying by Richie Incognito and other members of the Miami Dolphins, Incognito has been signd by the Buffalo Bills. Ray Rice, seen in a video punching his wife, is also expected to be signed by an NFL team this offseason. Has the NFL learned anything after a year of pretty terrible off-field press? Or have the incredible games and TV ratings masked growing social-issue problems for the league? Plus, how does this all play out for Michael Sam, who still has not received a contract offer?
