He's 41. I guess he has had his prime somewhen or meaby some fighters can have prime in older age than 41 :think?
I think Haye takes this one, but I don't think by KO. Jones would land enough right hands to keep Daivd honest and boxing his way to victory.
No disrespect to Jones, but definitely Haye. Guillermo doesn't have nearly the size advantage he's accustomed to and that, combined with Haye's speed, would really exploit the defensive flaws that Jones is able to get away with against smaller men.
