He was a character from Rocky V played by real life heavyweight Mike Williams. He played the interim heavyweight champ of the world and Tommy Morrison’s character ( Tommy Gun ) knocked him out in the first round
Styles making fights and all that, the better fighter loses here. I don't subscribe to the 'weak chin' argument about Floyd but Tommy was a fast starter and his chin USUALLY held up until he got tired and lost his shape. I think it would hold up against Floyd and Morrison's athleticism, speed and explosive power takes Floyd out before round 4. NOT because Floyd is chin, because Tommy is so big, hits so hard and will fight with no fear. ....if it goes more than four Tommy ends up counting stars before round 8....
