Well. of course, Marvin was a great star here, having destroyed our best, some of them very good. I guess he was amongst the best pound for pound fighters. Virtually indestructable. He spends a lot of time here, talkng boxing and commentating on our boys.
I first saw Ricky Hatton a long time ago and I was struck by the controlled violence of his body shots, technically correct cannon-balls - no swinging involved. I spread the word here, but because he has only been available on PPv, a lot of guys have missed him, and his opponents tend to not last long. Now he will there to be seen against your top men. He is trying to wind up Mayweather to come out and take a shot, and will want Oscar I reckon. He also is gunning for your new NY upstart, who is great I have heard.
So what I am talking here is specifically the power of Hatton's body shots - the best body shots I personally have seen. And Castillo got some.
I am a great boxing fan, my first hero was Joe Louis, but I am familiar with all the greats, heavyweights from John L Sullivan - "I'll fight any man in the bar." Gentleman Jim Corbett, Ruby Roberts, Jack Johnson, Jack Dempsey. By the time I was twelve I had studied America's Great White Hope period.
I was well into Rocky Graziano, Tony Zale, Jake La Motta, and Sugar Ray Robinson, etc.
In 1927, my uncle fought Max Schmelling, the German champ who beat The Brown Bomber in round one, and later got obliterated by Joe. When i was a little kid my uncle used to train me in his gym.
OK I'm getting carried away here - I'm done.
In answer to your question i would really have to back Marvin to have a great chance against anyone. Top of his weight, with very few exceptions. I was not suggesting that Ricky has established himself in that class, but watch this space.
