The Martial Arts industry changes a little at a time and I lived through many changes in my life from the Karate Kid days to the Steven Seagal Aikido days to MMA and now the globalization of BJJ.
Right now with the growing emphasis of training Police in BJJ, it is the perfect opportunity for Krav Maga and other combative arts to partner together with BJJ to help serve what I believe is going to be the next trend in martial arts.
A powerful BJJ program with its grappling dominance as the nucleus with a powerful combatives piece to fill in the gaps re: hand-to-hand striking and weapons (edged and impact) training. We just might be seeing a new style of BJJ emerging.
