There’s no doubt a ton of this stuff going on in the league, every day. And Gruden rightly suffered consequences. The fact that this was bright to light through an unrelated investigation and then leaked in strange ways to the media, however, suggests the league office doesn’t have much interest in addressing it in any systematic or serious way. It’s going to have a chilling effect for a while, but if I had to guess most around the league won’t learn the right lesson.
As for Goodell, I’ll never understand the owners’ allegiance to the guy. The pessimistic view is that they keep him around because he’s amoral and part of the old boy’s club, but then his office selectively snipes prominent people. He’s really the worst of both worlds.
