Cotto had more success at other weights then he did at ww he was never the man at that weight. Funny enough he became the lineal champ at 160 with out ever fighting there but that different story. Cotto best wins at 147 is Zab who kinda lost most of his big fights and Shane when he was 36 which was md very close fight. Cotto was good ww but i think 140 was more of better weight option 154 worked out because he had speed until he got owned by trout.
