Marquez resume after Mayweather:
Fedchencko (who he?) 140 lbs W
Pacquiao (2x) 143 lbs L
Ramos (who he?) 143 lbs W
Katsidis 135 lbs W
Juan Diaz 135 lbs W
Mayweather 146 lbs L
Aside from Pac, he fought two unknown fighters which cannot be considered a sterling record. Marquez is overrated in the welterweight.
He waits only for Pacquiao, and avoid the rest.
