George Karl is in no way an upgrade over Rick Adelman, in fact, rep, or acheivement, and unlike Rick, has the additional negative of being a mini-Larry Borwn who inevitably alienates his star players. That would be boneheaded.
That said, I have a hard time seeing the Maloofs sucking it up and putting their big $$ long contract confidence in Rick again. So I think they will be looking for a change. Fact is however that the grass is not always greener. Silas? The Van Gundy Bros? Solid coaches all. But which among them exactly has come closer to a title than Rick? Brown after his mega-dollar Knicks debacle? Wilkens in his absolute lottery team dotage? Don Nelson, who is WORSE than Rick in the ways we theoretically want to improve, and is absolutely notorious for never coaching his teams in a way that can lead to a title?
Here's a name for you -- Rudy Tomjanovich? Horribly overrated, pseudo-fired by our rivals down south, but at least with the dissipating reek of championshups behind him?
Or...Coach K? Take the ultimate college coach risk?
