>>10717699Nobody really 'wasted' their career. It was usually an offshoot of WWE with older talent that was basically done anyway (Booker T, Kurt Angle, Christian Cage) These talents were not wanted by WWE for one reason or another. Age, drug usage, rat face. It didn't matter.
But for the sake of conversation I would say Samoa Joe blew his prime years wrestling in TNA for little money and doing his indy feds. In the end, he still went to WWE.
