No need to apologise.I have limited understanding of BJJ.I am sure Mr Garcia is competent at his own method.All I am saying is I do not see his art bearing any real resemblance to Aikido . Cheers, Joe.
In the clip Kevin posted you see things that make no sense from a Judo perspective, but BJJ rolling and Judo randori are different games.
OTOH, there are similarities between bjj and aikido, but they are not evident in the sense of "techniques" (you are not going to see shihonage or ikkyo pins in bjj). The similarities are more in the flowing, movement, management of forces, relaxation...
