GSP has lost before we have see it, but he will get a rematch. Franklin has lost and had his rematch. If Silva was to lose and not get an instant rematch some if seriously wrong.
What year is it 2012? Silva has been holding that belt since 06. To put that in perspective, Jon Jones was still in high school, Chuck was the LHW king pin, Tito was a superstar, GSP had not won the WW title yet, Sylvia was the HW champ,..best of yet Pride was still around.
Chael Sonnen clearly lost but had his instant rematch, he just got suspended. Plus What do you do with silva if he loses? Give him Belfort,Okam,Stann,Bisping who all poses zero threat to him as they will stand up with him and get KO.
