How the heavyweight division stacks up

I'm not gonna rank them, i'm just gonna say who i think are in the same class with one another top - byrd, vk, toney although byrd has strugled to beat just about everyone, there's no doubting his skill or toney's either... while VK has the size, strength, chin... these 3 have to be favorites over any of the guys below 2nd tier - rahman, ruiz, brewster, wlad, sanders, brock i'd make the guys favorite over everyone else but the top guys 3rd tier - fres, golota, mccline, barret, whitaker, donald they've already lost to the above guys, so we know they dont belong. yes, barrett belongs here til he beats someone worthy, guinn and beck dont count unproven - valuev, peter havent fought anyone good enough to say where they belong
