All I ever hear from GSP is that technique is more important than size and power. Id love to see him prove it. GSP is one of the biggest fighters for his weight class. I do think that Silva could probably make 170. However I think the fight should be fought at 175. Up until GSP last fight with Condit I thought he could beat Silva. He might not be quite the wrestler that Sonnen is but he is pretty dam good. I can see him taking Anderson down and holding him there. GSP had a tough time against Condits constant movement on the bottom.
The main reason I want to see this fight is cause I want to see both fighters tested instead of coasting.
