I think Moore's heart and sheer determination would wear down the technically superior but smaller man.
Davey Moore would turn this fight into a war in which Simon had no chance of winning.Moore kayoes Brown in nine.
Brown proved himself more than Moore. I think Brown stops Moore in the late rounds. Moore never was a great fighter. He had 11 fights when he fought Duran. And rating him by his fights after Duran would not really get him a high ranking.
Moore. It's asking a lot for a welter like Brown to move up and take on a big jr middle like Moore. Davey would be twice the size of Simon from the waist up. I think he manhandles and overpowers Brown in this.
