I'm pretty sure Dan Henderson qualifies as a real wrestler. We all know what happened there.
I agree with Spin.Nobody at 185 has the physical tools GSP has and despite Silva's win over Hendo, Hendo without a doubt is the one guy who at least won a round against Anderson in the UFC. GSP is faster, better conditioned, has better striking and is way more versatile. If Anderson cut to 170, his size advanatage over GSP would go out the window and I think that GSP would be able to take Silva down, avoid being submitted and do just enough on his feet to stand with Silva and avoid getting KO'd. At 185 I think Anderson would win. At WW I think GSP would win.
A completely dehydrated and exhausted Lutter had Silva in a full mount. I'm sure Anderson learned from that and has improved since then, but imagine what might be possible with GSP. I also think that a fight like this would bring the best out of both of them.
Silva lost alot of fans and respect today
