Firstly...the NFL was a tax-exempt organisation? WTF?
Apparently, as a trade organisation, the NFL itself - not the teams - had such status. It's always been odd but, in the wake of issues like the Washington franchise's nickname, concussions, multiple occurrences of domestic abuse...and murder, the NFL has come under more and more pressure to clean up its act or lose its tax exemption. Well, in lieu of the former, the NFL has accepted the latter.
Goodell is cementing his place in history as one of the worst major league commissioners in history (a very low bar) as well as a pretty awful human being.
