Out of all the SS6 fighters,who would've given him the most trouble and who would've have given him the least?
Nobody would've given him that much trouble tbh. Ward is the best guy in the tourney and that would be a replay of the first Hopkins fight. Ward would make it the closest, but that's not saying much. Both Jones and Calzaghe would walk this.
Ward has enough ability to make some rounds competative, maybe losing something like 116-112. The best any of the others can hope for is to lose a shut-out rather than being ko'd.
