The only welter champ that could beat middle champ was Sugar Ray and he was Both welter & middleweight champion!
GGG would stop Floyd once he could run him down! Floyd would be sliding from corner to corner at break neck speed! I doubt most fans recognize that GGG has heavy hands and they don't really know what that means! Floyd does and theres no way he fights GGG!!!!
Floyd-5' 6 1/2" 147

GGG-5' 10 1/2" 160lbs

only a great welter can move up to 160 and win, Floyd is not a great welter! His best weight is at 135+ not 147! He doesn't have the power against welter greats from the past, he's to small! Ray
