By nature Silva isn't a fighter whereas I GSP is. Silva has, can and will fight but not like GSP. If GSP fought safe I think he could have avoided the Serra fight but that isn't him. I think GSP has cleared out 155 and 170 and that is what tips it for me but I understand the Silva choice.
GSP has only had 3 successful title defenses out of 4 total defenses. Those coming against Fitch, Penn, and Alves... and being knocked out by Serra. Anderson Silva has had 10 straight wins in the UFC, 6 successful title defenses against Lutter (although Lutter didn't make weight so officially wasn't a title defense), Marquardt, Franklin, Henderson, Cote, and Leites. He has also moved up to 205 to brutally knock out Irvin, and Griffin. The answer is Anderson Silva by far. Especially considering that GSP was knocked out by the TUF winner in his very first title defense. GSP is great though... and is a very dominant fighter. One of the best Pd 4 Pd in the world.
true.. i think that is why many picked silva as the most dominant champ. He has look good since he came to the ufc. The guy is undefeated and i don't think anybody at 185 right now can beat him. we'll see how vitor belfort look against franklin next. If vitor can look good then he can get a title shot soon.
