He wouldn't be in my hall of fame list. His two biggest 'victories' were in fact losses. He beat Stevie Johnston but correct me if I'm wrong Johnston is no hall of fame fighter?

Wins over Lazcano and Diaz mean about as much as Hattons wins over Urango and Maussa.

So it comes down to three opponents.

Diego Coralles, 1 -1 got KTFO in the first fight, won by cheating in the second
Mayweather 0 - 2 lost both times, first fight was controversial but he still lost, second was definite win for Floyd.
Casamayor 1-0 Not seen the fight myself but was supposedly very close and could have gone either way.

Not a hall of fame resume imo
