The Heat used to be my least favorite team WAAAY before Shaq went there. I used to hate Alonzo Mourning, Tim Hardaway, Vahson Lenard, Jamal Mashburn... that whole crew, mainly because I thought they were the most boring team in the league to watch and because the players were always fighting with other teams. That and honestly, Zo's always seemed like a jerk to me. After they left, I was neutral with them. I didn't necessarily like them, but I didn't hate them either. I liked Odom but that was as far as it went.
Now I've soured on Shaq just because of all the stuff he's said about the Lakers organization. Some of it's warranted, but most of it's just stupid, juvenile, childish stuff. I was cool with him until he started all that up, even after he demanded the trade.
The rest of the team I couldn't care less about one way or the other except for Zo, who was eternally my most hated player. Wade's fun to watch play though, he's super-confident, always aggressive and an all-out competitor, which are the same reasons I like Kobe.
Bottom line: do I like the Heat? No. Mainly because of Mourning and Shaq.
