In no particular order:
Lakers
Heat
Celtics
Nets
Knicks
Spot on, but maybe the Thunder get more hate than the Nets nowadays. Around NBA fans that would be the top 5 most hated teams.
My top 5 is
1. Lakers. They're the enemy, they are the New York Yankees of the NBA, and they also claim to have 16 championships as "LA Lakers", when they only have 11. About the players, Kobe is disgusting, and Howard is a dirty clown, just as Metta World War. Number 1 far ahead of the rest.
2. The cHeat. They are pretenders, they are ESPN's pet and they've used the refs two straight years to get past OUR Celtics. But they're sort of newcomers, a footnote. About their players, I only hate Karate Hamster Wade. LeBron is an idiot, but he's too good and he outplayed our banged up team in a single game. Bosh played well, too, and their role players... I don't like them, even less against our team, but except for Chalmers they're likable guys.
3. Da Bulls. Jordan Rules, that's it. I hated them, and like teenage love, you don't ever forget teenage hate. Their current team is nice, and Thibs is a great guy, nothing to hate there except for the "Rose is better than Rondo" media story.
4. NY Knucklebockers. Pat Riley years... I wanted them to beat Da Bulls, but they always let me down. Then, the Hype around the franchise makes them dislikable. No hate for the current team of chuckers.
5. Any other team that's showboating for a win against the Celtics.
