Jeet Kune Do would be seriously constricted in MMA....This "style of no style" so to speak has no rules as well....MMA does...so its null and void..

Thats like a boxer not being able to use an uppercut or a hook to the body...

Jeet Kune Do allows every part of your body as a weapon, and also atks all of the vulnerable areas of your opponent...This is not for sport...I don't know how else to explain it...
