If you look at any long standing champ,there'll be a guy on the list and youll look at his record,and find yourself saying "Huh,he looks pretty good"then you look at his record,and hes completely tanked after that fight.
A good example Rudi Lubbers,he was 22-1 when he fought Ali
He ended up 29-8
Is the guy exposed?
Mentally damaged?
Whats your opinion on why guys tank like that
