Nick used a variation of the gogoplata and you don’t have to be able to pull your leg over your head… its actually really easy to pull off with limited flexibility especially on wrestlers that like to stack you but are used to seeing triangles coming they damn near gogoplata themself.
you can simply pull your opponent’s head down with two hands
^thats what nick did.
I came up with another version of that where you pull down with one hand and the other hand is pulling down but its not on the outside (clinch style) but you slip it like an underhook underneath your leg that is by their neck so that when you squeeze your bicep is pushing your leg up and your hands are pulling their head down kind of a push/pull steering wheel motion.
It’s not a huge part of the 10th planet system but its kind of like their signature move you’ll see a lot of dudes attempt in MMA now. Cole Miller (i think) pulled it off in WEC or maybe that was someone else…anyway.
The rubber guard is the huge part of the system and basically if you can get your opponent in rubber guard there are a limited amount of ways for them to escape and a few ways for you to deal with each of those while there will always be variations excluding those slight adjustments eddie basically has a flow chart in each of his books that show you exactly what you need to do
kind of like how Nakamura had flowdrills when he taught shooto… and a lot of bjj schools have something similar…
example, if you get the armbar, and they try to escape, go to triangle, if they try to stack you look for the oma plata.
But eddies whole system is a LOT more comprehensive and accounts for damn near every opportunity your opponent will try to take advantage of.
It’s like a choose your own adventure book… from this position your opponent has only 3 options, you have two pathways from each of those options…but it has to be intuitive because there isn’t time to think.
But if you’ve drilled all the way through these positions you’re like 10 steps ahead already.
Thing is it’s not just rubber guard, he has a game specifically for the twister, darce choke (works great if you’re a sprawl and brawl type) for the half guard (top and bottom)and more AND they’re all connected.
it’s a pretty brilliant bjj derivative if you’re open minded. plus because most people haven’t seen it/experienced it they fall into it’s traps easier.
also unless you’ve drilled that shit A LOT it won’t be intuitive to you so most people just try to slap it on and cant set it up effectively…
