Isn't this the same thing we were hearing before the Henderson fight? Hendo was a strong wrestler with a Gorilla like clinch who before their fight only lost twice by submission to the Nogueira brothers. We saw how that fight went.
Dan Henderson's ju-jitsu game isn't even in the same galaxy as Weidman's who was going to points with world class grapplers such as Andre Galvao as a purple belt, and that was three years ago. Weidman is a monster on the mat.
