Yea i know Duane he beat Larry Holmes in 1976 Olympic trials didn't he ??
exactly : http://en.wikipedia.org/wiki/Duane_Bobick

Duane is the guy form a family full of boxers (4 boxers brothers I think) he was so hyped because of his white pedigree at that time (70's) that he was saw as the Threat for Ali....until he was knocked out by Ken Norton in one round :-)

this guy (duane) could punch, for sure, but only against static opponent and glass jaw average guy....http://www.boxrec.com/boxer_display.php?boxer_id=15810

anyway, I have more pitty for him than anything else, but when I met him he went too far in way of cursing people...(but he was drunk).

I heard also some identical stories about Tommy Morrison, but don't know if it's true....
