gsp vs. silva would be unreal/logical, it seems like a possibility. Both fighters have completely destroyed their weight classes.
silva vs. machida would be amazing as well. Anderson said they are friends and refuses to fight him. Dana White said he's not buying that shit in some interview I read.
The 170, 185, 205, and heavyweight champions in the ufc represents the cream of the crop in mma no questions asked.
I can't stand Brock and would love to see him fight Fedor. Brock's size and athleticism are the only things that keep him on top. His technique is garbage and I would love to see Fedor put him to the test.
