5. Rajon Rondo, Boston Celtics
Apparently, Ray Allen hates Rondo and the young point guard is one of the reasons Jesus Shuttlesworth signed with the Heat this offseason. Rondo plays with an arrogance that rubs folks the wrong way, sort of like Kobe Bryant. But if it weren't for that supreme confidence he wouldn't be one of the best floor generals in the game today.
Rajon also lets his emotions get the best of him. Like the time he wore a funny jacket and stepped to a cameraman filming him wearing it. Or like when he purposely bumped into a referee during last year's playoffs, or when he started the mini-melee vs. the Nets last Wednesday night. Rondo needs to chill before Danny Ainge finally decides to pull the trigger and trade him and his rollerskating addiction out of Boston.
