i think so silva should retire now.i mean after getting brutally KTFO by dan and cro crop,i think so he should retire.i really don't think he can comeback from his embarassing defeats.he can only beat those little japanese fighters.he just can't beat the big boys of MMA.if you can see his past record he got beaten by ortiz,arona,belfort,mirko,mark hunt,dan etc..against real fighters,wandy is a pussy
