Here is a great clip from over 15 years ago of Carlos Machado fighting Mauricio Pereira at the 1997 Pan Am's! From the looks of the poll on your right (one last day to vote if you have not done so) you all would like to see more instructional / tutorial videos here on the Ground Never Misses, and I cannot think of a better lesson then from red-black belt Carlos Machado!
This epic battle shy's in comparison to what Pereira went through in 2006. Mentor to the likes of Fabricio Werdum, Pereria was shot to death over some trivial dispute June 14 2006. He was a 3rd dan in BJJ. RIP
Remember you can get on the mat with Carlos this October at the 5 Brothers Camp in Dallas, TX. Meanwhile study the above video, lots to learn from the multi time champion!
