There is no reason Roger Goodell should remain as commissioner of the NFL. His pursuit of Tom Brady and the Patriots for what remains an alleged misdemeanor on a par with corked bats or excessively curved hockey sticks has managed to demolish the powers of his office as regards disciplining the players in the league. (Goodell already was halfway to demolishing those powers with his bungled handling of the Ray Rice situation.) It has exposed him as a faithless and arbitrary jefe presiding over a banana republic of his own mind. And he used one of the NFL’s signature players, a guy who really is everything the NFL claims to want in its players, to do it.
