white kid at the top in the black tank top...he was 13 in this photo (1987)...
If he was 13 in 87, that would make him about 37/38 now...using your clues that he is white and also that he has a diverse group around him, he has got to be either an American or a Brit...I'm going with Danny Green as well.
Could be (Green), but why would he be in the U.S. when he was 13? Danny Green's an Aussie and most of his fights took place in Australia....
Oh, OK I guess I was wrong in my guess then. :sad6:
I'm not saying it's wrong. I didn't know Manfredy was a WBA champ. You learn something new everyday.
