I did mean Sonnen, you are 100% correct. Not sure how I screwed that one up.
Silva actually does have pretty bad TDD. Blame it on his unwillingness to change his stand up stance or style, but he leaves himself open. I'm not just saying because of the Sonnen fight, I have said it about him for a while. Granted this is the third time in the UFC he has proven why he doesn't mind the ground as he won by sub again. I think he just doesn't care. To get him down you have to come within his striking range, and if you get him to the ground his lanky limbs make him just as dangerous standing up.
I honestly think you're right on this... I just don't think he cares if you take him down. He seems to be comfortable in either position.
