As we all know, GSP is very big for a welterweight, and its hard to believe he can stay at 170 pounds. At some point I see him going up to Middleweight if Sherk or Penn can beat him for the title. So if this happens, Will he face Silva for the middleweight title? I personally feel this would be the greatest fight in MMA history if it went down. It would be hyped up like no other as well. I personally feel that Silva would destroy GSP. GSP has never fought a fighter quiet like Silva, and his Muay Thai is probably the best in the world right now.
