I have just recently got into boxing and I am confused as to the difference WBA WBC and IBA titles. I see that Nicolay Valuev is the WBA champion currently and also has a perfect professional record, but is ranked 8th in the world. Shouldn't he be at least 3rd as a champion? Also why don't the three champions box eachother to find an soletary champion as which is found in other sports, its all very confusing and your guys help would be greatly appreicated. Thanks.
