Most "promising" fighter who never really blossomed?

[Mark TKO]

two names spring to mind that are already mentioned

Bojado (what the hell is he doing now )
Valero

also Cassius Clay - that guy had it all but went off the radar around 1964 , he was the fighter Ali could have been


and yes Naz never achieved what he should have. Ok he 'blossomed' and became a superstar but the regularly used term on here that the fans were 'short changed by a career' has never been more appropriate.

He wasn't as good as a lot of people thought - but lets not forget he hasn't officially retired yet so there's still time for him to prove us all wrong
