He doesn't have enough mobility to stay away from any quick fighter (which is also probably why he fights at HW instead of cruiser).
Haye's quick and has heavy hands but as Atlas pointed out when Peter actually does throw his punches they are very fast. Haye also loops his punches and his footwork is bad. He trips over his own feet alot. I see Chambers as the much more fluid and complete boxer and his excellent left jab and terrific chin will be a big problem for Haye. I would actually pay to see that matchup for a reasonable price. I smell an upset and I admire both boxers.
Chambers is pretty talented, but he is way too fat for a fighter with his style. I don't get these heavyweights...they spend hours in a gym EVERY day and they're still sloths. Are there hot dog stands that come by after each round of sparring?
