Sanchez Vs Guida -- SO CRAZY THE INTENSITY
GSP vs Serra 2 --- or GSP vs Hughes (all)
Couture vs Tim Sylvia was just simply amazing to watch...
And the obvious... Bonnar vs Griffin at the end of the untimate fighter 1.... that was a fight that will be remembered for all time.
Rua vs Hendo was great too... and there are a TON more.
