I know a lot of people like to claim that Dos Santos has the best takedown defense in MMA, and I know there have probably been literally thousands of threads started on this topic, but I'd like to point out a few things I've noticed about JDS that go unmentioned in this never ending debate. 1.) Dos Santos doesn't have that good of TDD from a wrestling standpoint. The few times we've seen another fighter get to his legs, he's been taken to the ground somewhat easily, although he's gotten back up. Carwin basically dropped him to his butt from all fours, and Nelson, who isn't a good wrestler, would have put him straight to his back 3 times if not for the fence. 2.) JDS' boxing is what makes his TDD so good. I know that sounds a little ridiculous, but that's what makes Dos Santos so special. His ability to control distance with his boxing, his footwork and punching power are the keys to his takedown defense. His jab allows him to keep people outside of takedown range, and his power in both hands stops anyone who gets inside takedown range from really committing to any shot they take. While I've said that I don't believe he has the best actual takedown defense, I believe he is the fighter least likely to be taken down, if that makes sense, because of the factors listed above.
