I think one of the earlier poster had it right Mosleys damage was more complete the way he walked Margo in the clenches to take his legs. His body work was better than Cotto's. Punches were more powerful, his head didn't get snapped back because Mosley threw more hooks instead of straight punches and he didn't let the pace of the fight get away from him the way Cotto had done.
Swelling around the eyes is just superficial damage. Mosley beat his ass to the canvas twice, so Mosley did more real damage.
Cotto connected in high volume but his demnise was that he never was able to get leverage on his punches, SSM did.....
I will said this..Cotto inflicted damage to MArgo like no one before him, evethough he was able to sit on his punches and get the proper leverage, so I'll put it this way.."SSM finish what Cotto started..."
he came out the cotto fight king of the world and a true warrior and he came out the mosley fight beaten up broken with his career looking like it might be in tatters. i think on all fronts mosley hurt him the most
not so fast...Did you see Margo's face after the fight?...and Cotto never got leverage since he fought backwards the entire fight....yet, he inflicted enough damage on Margos face to have severe swallen and perhaps softening him for SSM
