A great compilation of leg drag passes by those tricky Mendes Brothers. This is a very subtle movement, but it asserts positional dominance which leads into submission's most of the time with these two!
UPDATE: The Mendes boys are coming to Portland in April. This is a bit too rich for my blood, but for all you loaded gangsta's this should be a huge seminar!
Enjoy and study on this, if for no other reason I am going to start playing with it in rolling.
