Re: Which fighters between 140 and 160 would Mayweather lose to?
I think Mayweather has slowed a little but still would start favourite over almost everyone at 140-154 and quite even at 160.
I think Matthese would have a under-rated chance if he pressured Floyd with workrate and combinations. Pacquaio obviously has a chance but Mayweather would be favourite. As a poster above said, Golovkin and Alvarez are untested still so a little unknown but from what I've seen both would have some chance although would be underdogs in the betting (unless at 160). Martinez possibly has the best chance of beating him especially at 160. People might laugh (I don't blame them) but I would give Khan a small squeak too, I think his speed might give Mayweather problems in early rounds.
