I misread the title as fattest heavyweights of all time lol. Came in to nominate Big G. As far as fastest, Ali is the obvious answer along with tyson. One answer that not many people would think of is Dempsey. His hands were pretty fast throwin those wild combinations. Not saying he's the fastest by any stretch of the imagination tho
I'm going with the two obvious ones which are Tyson and Ali. I don't know why people assume heavy's must be slow when the fastest sprinters on the planet are usually 210 lb. Also about the Haye argument I don't even see how people think that was a legit KD by Barrett, it was not scored as one. Haye also is a fast and accurate counter puncher but his feet are not that fast and neither are his 5-6 punch combo's when comparing him Ali Tyson, in this day and age he's probly the fastest around along with maybe Vitali.

David Haye's speed is overrated. It is very good when it comes to single shots, particularly his right hand counter, but his combinations aren't very fast because he gets sloppy and loses his balance. In no order: Muhammad Ali Mike Tyson Floyd Patterson
Jones was a heavyweight for a minute, so I guess it would have to be him. As far as true heavyweights, I would say Patterson.
dempsey was fast as ****, watch his hands at :54 [ame]http://www.youtube.com/watch?v=EI-pD8VIeN8[/ame]
