Hey there,
Well, calf kicks are now done so often, but no one is checking them....that is one thing missing.
The next, would be what I call my Anti-Cage Techniques....some guys now are doing the throat/chin shove technique which is good, but all should be, and that is just the easiest technique I have an entire system.
But right now the evolution is Range 5 Neo Striking, blitz, off rythem, switch stance, shift, switch punch attacks. Only a few are really doing it, and understanding how the use of calf kicks and knee kicks can keep you with footwork safely in range 5 where most fighters can only fight to range 3. I mean most are not good at kicking, other than close range 3 round kicks to leg.
knowledge of much more subs would help. Now the leading is the guys that pay attention to front headlock series that I teach and advanced guillotines....it is transitional stuff now not so static that can lead to subs. Christian Lee and his sister are doing it and I share vids with them. U do see some seem to pay attention to the guillotine and front headlock series vid I teach........chin strap or then going to Schultz Choke as the starting point....but everyone is missing when the few guys have gone to Schultz choke for a few seconds.
Other leglocks from top position as in my 5 leglocks you stay on top is missing, like the reverse toe hold now a few have tried, one of which I taught, and the toe pull I made up.
If you enjoyed my answer, reply back, cheers
