Golovkin would still smoke Cotto's bones even if he had Sergio's gammy knees and Margarito's crook eye. In fact, it wouldn't make any difference if Cotto was allowed to wear Margarito's wraps either, he'd still get bashed.
Cotto has the style to outbox GGG but in my opinion he's to small for him and with pressure from a bigger with time Cotto will get tired and get stopped late maybe but if he can use his leg for twelve rounds Cotto can probably beat him and it's a big if
Believe me when I tell you that if a crude fighter like Marg can trap Cotto you can bet your ass that one of the most skilled pressure fighters in our era is going to cut down the ring quickly.
THIS I hope GGG gets the chance to unify MW titles and that he gets recognitions and name that he deserves. Same time I wish all the best for Cotto and that he won´t fight GGG. He has options and he has already done so much for boxing - Cotto doesn´t have to prove anything.
Cotto doesn't need this fight. Then again he can come back from beatings. PAC ran him out of the ring. Cotto is legit though and is vastly more skilled than the Daniel Geales etc.
