The dominance of the Klitchko brothers is impressive, but the quality of competition faced by the Marquez brothers edges it for me.
I love the Brothers Marquez... but it doesn't get any better than the Klitschkos. Multiple reigns, bajillions of title defenses, many, many highlight reel KOs..
At first I was all..."Man, he's crazy! They ain't done ****!" Then a second later.....brilliant! :good
I love Miguel but having the Cotto BROTHERS and not Canizales or Galaxies...come on. Dirrells ahead of them too? Good fighters, but what the f...
It was close but I voted Marquez. Rafa and JMM have put on some fights the Klitschkos could only dream of.
Size doesn't matter; it's how you use it. The Marquez brothers' multi-divisional resume exceeds that of a pair of Heavyweights operating in a historically weak resume, however dominant they may be.
