I was a big NBA fan in the 80s. Then after the Sprewell incident, I lost most of my interest.
It wasn't his choking the coach. That was totally wrong, but at least I could understand (but not excuse) someone screwing up in an emotional fit. What bugged me was the support he got from so many other players afterwards. As I recall about a dozen of them got together and called a press conference to say that they supported and backed Sprewell on the issue.
I quit going to games and for the most part I quit watching it on television.
