This is the best answer on the subject and the correct one.
A lot of fighters rack up 30-40 undefeated fights on their record then meet a better class of opposition and move up weight divisions, it's only a matter of time before they encounter a fighter whose style will
not suit them. Forrest V Mosley being my example. Mayorga V Forrest being another.
Once a fighter has established himself and becomes a World Champion every fight he has from then on is usually against a top ten opponent, you can't win em' all.
