Yes but what has that got to do with the improvements he's supposedly made ? yes he hadn't fought anyone prior to fighting Graham Earl, but that isn't my question. Skel stated he's made major improvements.
He's fought better opposition after Graham Earl obviously, but he didn't win those fights by making major improvements. He won them by fighting the same style he always has, and that's coming forward showing alot of bottle and and out willing his opponents.
And the reason he lost two fights is because he always fights the same way, by coming forward providing alot of action but also leaving himself very exposed. Which is why he got KO'ed by Joel Casamayor and outboxed by Juan Diaz.
It's no different to Arturo Gatti, who always fought the same way whether he won or lost. Or whatever type of opponent he fought, he only started to box more when he went with Buddy McGirt. But he still easily got lured into a brawl.
