Pac - Mayweather - For the Lineal (ring) WW belt?

http://www.ringtv.com/ratings/welterweight/ Fighters recognized as champions by The Ring are rated at the top of their division, with the top 10 contenders listed below. Championship vacancies can be filled by winning a box-off between The Ring's number-one and number-two contenders, or, in certain instances, a box-off between our number-one and number-three contenders. The only three occasions when a fighter will lose his championship status are when he retires, moves to another weight division, or is defeated in a championship bout. The Ring Ratings are compiled by the magazine's editorial board, with the participation of The Ring Ratings Panel of boxing journalists from around the world. ___________________________________ 1 more thing, if berto wins, where would you rank mosley and berto in the WW division?
