The six-game duration of the suspension was not random
Remember, Robinson first decided she was not starting from a six-game baseline but from one of three games or fewer, based on precedent set by other nonviolent sexual assault cases. As "aggravating factors" (that is, reasons to increase the suspension), she cites Watson's "lack of expressed remorse and his tardy notice to the NFL of the first-filed lawsuit." As "mitigating factors" (that is, reasons to go easier on him), she cites "he is a first-time offender and had an excellent reputation in his community prior to these events. He cooperated and has paid restitution."
Very interestingly, she also notes the league could have placed Watson on the commissioner's exempt list last year and chose not to, which she appears to think means the league didn't consider his behavior worthy of such punishment until it saw the public reaction to it. She makes that clear in her conclusion when she writes, "The NFL may be a 'forward-facing' organization, but it is not necessarily a forward-looking one. Just as the NFL responded to violent conduct after a public outcry, so it seems the NFL is responding to yet another public outcry about Mr. Watson's conduct."
Judge Sue Robinson made the right decision, imho, and the league should stand by her decision. If they don’t the whole NFL disciplinary process is a joke going forward.
