I answered your question. You obviously didn't understand the response. Mostly because you fail to understand the concept of "precedent." Like how Marshall's prior arrests for domestic abuse and suspension, which was reduced to 1 game, show that he has a history of violence towards women. Yet when a cop arrests him for doing it again, it's "nothing to see here, move along" because the charges were dropped, as if it never happened and the cop imagined him hitting her. The same thing with your unfortunate citing of Tank Johnson, who was first arrested for having a gun in his car, before he was arrested again for having guns in his house and violating parole, utlimately getting suspended for 8 games. And in both cases, Goodell offered a chance to reduce the suspension by 2 games. Why not in Lynch's case? What precedent did Lynch set? Exercising his 5th amendment right? Oh, the humanity!
Goodell is a joke. But obviously he's not the only one.
