Who is/was the NBA's greatest dunker

Now, obviously the person that most fans will jump to has to be the great Michael Jordan. I however have a different opinion. Now while I think MJ is one of the best dunkers and certainly the best NBA player in history, I am not sure if he was the greatest dunker. I look towards the likes of Vince Carter and Jason Richardson. They brought excitement and flash back to the dunk and I think the 2000 slam dunk contest was the best so far. Some others of note were D Wilkins, Spud Webb who were also master of the art of dunking, but I can remember watching the contests of Carter and Richardson and thinking that these men were true innovators. The most recent dunk contest have not been as great as they haven't grabbed the fans attention as much as those prior. I think Jordan is the greatest all around NBA player of all time and will go down in history as such, but who do you feel is the greatest dunker?
