I've just always thought that the beef was overstated...at least when it comes to how it effected the success of the team. They may hate each other's guts, but that's not what was preventing this team from performing. I don't think you need to be friends with your teammates (it's probably better if you're not), and the main source of the frustration was the fact the team just was stale and not very good. Keeping almost the same exact roster and not introducing new faces/personalities did not help.
People put way to much emphasis on the personal beef between the two and not enough on the failures of roster construction and coaching. If Don and Rudy were BFF's, nothing would have changed about our playoff fate the last few years. If we had better coaching and roster coaching I think our fate would have changed, even if they don't like each other personally....but I'd speculate there'd be no drama to report if we were succeeding on the court as has been always been the case.
I really don't want the FO failures to get swept under the rug because of the drama. This team didn't fail because of personal beef, no matter how real it pales in comparison to the obvious on court/roster issues.
