I keep on wondering why people keep on bringing up 154 pounders as potential opposition for Mayweather, why should he go up there again? Karmazin, Forrest, Quartey would add nothing to his credibility... if he loses to them there are excuses, and if he beats them there are excuses. The only person who would be worthy is Spinks, and even he isn't a very big name, and that fight wouldn't be exciting. Mayweather would walk Spinks down and eventually KO him. The only fights that should be considered are against Dela Hoya, Cotto, and MOsley. Williams is too green and too potentially dangerous for this fight to happen right now, what Williams needs to do is fight a big name and get people really talknig about him.
