One thing no one seems to be talking about in this case is the anti-trust exemption the NFL enjoys.
After the Ray Rice fiasco, the Senate had a lot of discussions about stripping the league of it's permanent anti-trust exemption and requiring some form of reapplication, perhaps every 5 years, and only granting anti-trust exemption status if the league was on its best behavior in terms of handling DV.
BTW, Roger was his typical reactionary self and applied a indefinite suspension to Rice, but a court overturned that suspension saying it was arbitrary. There's that word again. That's when Roger made up the 6 game rule, which was NOT collectively bargained. The league got the owners to agree but refused the NFLPA request to collectively bargain this change. So anyone saying this suspension (at leas the 6 game part) is part of the CBA is simply wrong.
