Margo is not that big, Boxrec lists Cotto as 5'7, half an inch taller than Pac. In weltereright terms Margos only half an inch taller than Oscar, Mosley is 5'9. Cintron is 5'11, Carlos Quintana is 5'9 1/2". With that said I think it will be a good fight.
Does Margo speak any English not that it matters, just would help now that he is hitting the mainstream.
I was going to write a long rebuke, but this is not the right board for it. I'll just say I hope Shane surprises Tony's ass and goes out on top.
margo will come in easily 15+ pounds above the welter limit come fight time. mosley will probably weigh in the mid-150s during the fight. that's about an 8-10 pound difference in fighting weight.
