The title means ****, it's who holds it that matters. The WBO light heavy doesn't mean much because Cleverly won it in bed. However I'd say Bradley's 140 version matters a lot because he won it from the #1/2 guy in the division at the time.
rocky balboa sure as hell dont all the other belts were in that film the other night except for f w a n k s belt
Joe Calzaghe held the WBO belt for nearly 10 years fighting tomato cans so that tells you all you need to know about the organisation right there.
