No doubt it's chambers followed by Peter. Sosnowski, Briggs and Ruiz were/are poor. Harrison is laughable. Dimitrenko/Chisora are below Peter but above the poor group.
Chambers by a country mile.. but it's true the list is pitiful. Chambers actually isn't a bad fighter, he just had no chance at all against the guy he was up against.
Chambers is the only one on the list that actually beat several top 10 fighters to earn his title shot. He also looked good against Povetkin before running out of steam. He's a good boxer/puncher and actually got himself into great shape for his title run, unforunately he was no match for Wlad.
chambers, by a mile. and he wasnt a **** poor title challenge at all. he had beaten brock, peter and dmitrenko, plus had a close defeat to povetkin. he was clearly one of the top rated challengers. and wlad beat him senseless.
