He is my favorite player in the NBA, but if I weren't a Celtics fan, his game and antics would be hard to tolerate. For one, whenever he puts the ball on the floor and tries to get to the hoop, he has a pained look on his face which looks as if he being stabbed by 100 needles. He has that look perfected, and combine that with his flailing limbs and his ability to use props [wheelchair], and what you have is a guy who can annoy anyone.
Hard to watch...
There is nothing I hate more than great size wasted. Yi is 7 feet tall, and listed at 250 pounds. However, after watching him play, there is no way he weighs more than 220. He looks like a stick bug running around out there. I don't think the man has one post up move in his arsenal, rather he is just a side-show act in New Jersey, taking jump-shots like he was a shooting guard.
I guess the Brazilian Verejao thinks he is playing soccer out there because all he does is take charges. I don't know how a guy who is 6-11 could be falling down with such force when a 180 pound point guard runs into him, but this guy does it time and again. Compound that with his ridiculous muppet hair-cut and his utter lack of skill, and you get a guy I cannot stand.
Honorable mention: Lebron (obviously), Kobe Bryant (hating, I know), Matt Bonner/Brian Scalabrine (They might as well be one person).
