Anyone who trains with me that has asked me about Judo in Jiu-Jitsu knows I will say the following.
You have to do one of the following:
A) attack with a footsweep and not overextend/expose yourself to a counter
Jacare was doing this before it was cool and before the Rafa Mendes pump fake ankle pick that's en vogue these days:
B) get them moving
C) take advantage of their poor posture (Sumi Gaeshi)
That being said, Travis Stevens and Jimmy Pedro are the latest to offer their expertise in this area with what appears to be some MGInAction style online training.
