Quinn was legit a tough guy. Did bodyguard work for a pro boxer. Was indeed a bit of a blowhard, though.
Him calling himself a legend is just asking for it. Yes, he was a "successful" pro, but he was never a competitor who was gonna become a "legend".
When he was in the WBF he walked on stage one year literally fat-as-fuck. They began drug testing and Mauro DiPasquale gave each of the guys a fat-rich diet that was to offset the loss of the drug advantage. Some kept using ... and added masking agents, and some shrunk dramatically. And Mike got fat and embarrassed himself.
He had good arms, back and pecs, but had weasel wheels. His claim of a 600-pound squat at 17, natural, is totally retarded. Maybe with a mile-wide stance and three-inch depth.
Sad what's become of him.
Concerning the dog-weenie sucking, I doubt it, but who knows. The industry is full of debauched shit.
