Yes those guys were anti-Rockets but Derek Fisher is unique in that he not only has damaged the Rockets' he has done it on multiple teams who are hated rivals.
I hate him, and not just because of his relationship with the Rockets. He's a one-trick pony, all he can do is shoot threes. Any other team, any other time, he'd be out of the league. But, he was blessed to be point guard on Kobe's Lakers with a triangle offense, so he stuck around. Then he forced his way out of Utah to the Lakers (as terrible as this sounds, I find it way too convienent that his daughter's treatment center just happened to be in LA, and that he had to be there with her (not that it really matters, since half of all games are on the road). That, and he's just an overall, dirty player and (fittingly) represents everything wrong with the NBAPA.
