sounds like a porn actor to me bill. i don't know if he'd sell with that big hairy butt. the director would be "focus on the girl, dammit!"
As I recall Valuev was born in 1973 so he is getting a bit long in the tooth. He's had a good run for a lumbering giant with minimal boxing skills. It is just a question of time before somebody gives him an embarrassing boxing lesson. Holyfield nearly did it, and if he had thrown more than 6 punches a round they might have given him the victory.
When did you see him on HBO and who was he fighting? I've never seen a Valuev fight on American TV let alone HBO.
