I've alwys considered Rudy T overrated. After that one year, and then one amazing playtoff run, his teams were disappointments every single year, and people just gave him a pass on it because he happened to squeeze in there for those rings while Jordan was playing baseball.
That said, I have been suggesting him as an option for some time now. In fact he is basically the last/only employable coach (unless you count the ghost of Lenny Wilkens) in the NBA who has been FURTHER than Rick (just as in winning the extra game or two and getting the title -- we can talk later about the comparative competition).
Not a disciplinarian (which is a GOOD thing). Not a defensive guru. But a nice guy who gets along with egos (key for Artest) and coould keep things moving forward. If he still has it in him physically.
