There are no "BIG 3". There are 2 great heavies (the brothers), 3-4 good heavies (Povetkin, Haye, Adamek, Chambers) and some really good prospects like Boytsov and Glazkov. What is making the division look crap, is the lack of good match ups (great and good heavies don't want to fight each other). Still though Heavyweights are better than cruiserweights
