I don't see how it'd be traitorous if you like the players that were formerly on the Jazz.  They're still the same players.
Anybody that says otherwise is clearly a moranic, Harpring-voting text-in poll Jazz fan.
Anywho, I don't watch a ton of NBA outside of the Jazz, but I do follow the Bulls, Nets (now, just to see how DWill is doing) and actually am enjoying watching the Melo-less Nuggets.  I'll never root for the Lakers because they're the Lakers.  Won't root for LeBron because he's a megadouche.  Won't root for Chris Bosh because he's a ninny.  Won't root for Garnett because he's a punk, and won't ever root for any player that sells out and joins a superpower team because they don't want to do it on their own, like a real man.
