Notice how there hasn't been a rematch for Silva in almost 4 years! no wonder he hasn't lost in so long. Fight them once and move on.
Why does anyone deserve a rematch? They lost. They had their shot, they blew it. No reason for someone to keep trying until they finally beat him, they either can or they can't. I have seen on here, people crying about how Nate deserves a rematch. Nate would get his ass busted in a rematch. Who deserves one either? Nobody has even came close to beating him other than a juiced up Chael.
The fact that he beats everyone is all the proof you need. GSP just beat Koz again after he beat him before. Big deal. What did that prove? Do we really need to see Cote get a rematch?
I just don't get the whole "he doesn't give rematches, beats them and moves on" thing. Seems like that's how it's supposed to go.
