During his prime, a lot of people were comparing him to Jordan until Lebron came along and surpassed him. He's obviously washed up and past his prime now, but when he was at his peak, I would say he was definitely a top 5 player. I know he's not very likable, and multiple sources have said that he's a jerk, but then again so was MJ.
I know he's not as physically gifted as Lebron, though at the same time, 5 titles is nothing to sniff at.
