That knee up in the middle sub (the first one), I saw that in a sambo video a long time ago (also in a jits mag). I think you get to hit that one time per person…if you’re lucky. Once someone gets caught with that…never again (from my experience anyway). Plus, to get that sub, you have to build space. When someone has you in their lockdown, they probably aren’t going to give you a lot of space, and if you force your way into creating the space needed to bring that knee up…they’re changing their path.
That second sub (the gi pant grab and gi sleeve grab). Never seen it before, but it looked interesting. May have to try a nogi version. Camera guy could have done a better job at getting an angle from the actual lockdown. Seemed legit though. Be interesting to see if anyone has a nogi version of this (with a better angle).
