Who will in win Pacman or Sugar Ray Robinson, uming both fighters are in their prime?

Honestly I think Pacman will win, even Robinson cannot even beat Cotto I think...And can he achieve his 100 wins if he fights today? Fighters now is different from fighters then..You cannot tell me of any sports where a 50s athlete can beat a 21st century athlete..All past records have been broken by a mile...I pick Pacman by KO round 8...
