I choose to believe this was a hard decision for Ray. I think it was no one particular problem that drove him away, but the collection of them made him believe enough was enough. All we have seen from him over the years was nothing but class. Although he was effective in He Got Game, he's not that good of an actor to fool everyone regarding his image.
But yeah, by the time training camp opens, I really don't wanna hear his name anymore. We can banter about him for the summer out of boredom, but he doesn't matter anymore.
