During the post-fight press conference in Atlantic City, New Jersey this weekend, newly crowned world middleweight champion Kelly Pavlik said he does not consider himself the undisputed middleweight champion of the world.  "I am not undisputed, being undisputed means that you have all four belts."  However, Pavlik is the lineal or true world champion, because he defeated Jermain Taylor over the weekend, and Taylor had beaten Bernard Hopkins in 2005 after Hopkins collected all four major titles.  The IBF championship is currently around the waist of Arthur Abraham, while Felix Sturm, considered the least accomplished among Pavlik, Abraham and himself, holds the WBA belt.
