In his podcast with Chris Connelly, Bill Simmons discusses a bit on Steve McNair and the world of sports athletes having mistresses. If you want to listen to just that, it's a bit after the 21:00 Minute Mark in the podcast. Lots of good points. Very interesting. Connelly brings up a GREAT point about how in some ways it isn't fair for McNair because he was such a brave and courageous guy, and for him to become branded the athlete who "cheated on his wife" is unfair because they all do it, and the complete reactionary moralizing and how unfair it is.
However, if you wish to avoid all discussion on this aspect of it, don't listen. They aren't harsh in any way, but they do discuss the details surrounding the situation and the subsequent effects on the McNair legacy. .
