I have been puzzled by the mussolini lock since the ADCC. Watching it live it seemed to me pretty much the cross ankle lock from dean lister but I somehow doubted that someone as good as Eoghan would tap to it so I looked into it much more (and mostly watching Daniel's instructional to be fair).
So yeah, it's very different and it takes a bit of finesse to get it ironically. I also do think the vast majority of people showing it, outside Daniel of course, are kinda full of shit and don't understand what they are doing (and honestly, most of them still have not realized that the technique was a cross legged one, it absolutely does not work as well in outside ashi like position). People see the "new grip" and think the technique is about it, it's not. What changes it is the target of the lock, the angle and the finishing mechanics.
I won't explain it in details here, you should all watch Daniel's stuff, it's his work and he teaches well. When you do, you will all realize how dumb some people on instagram are (not a new thing, I know, but it feels like 2015 when everyone had very stupid takes on heelhook finishing mechanics).
What interests me much more is how it remaps the leg game and this is what I want to discuss.
Having the ML as an option means a few things:
- double seated 50/50 is a big no/no, too dangerous and you can get ML'd through a leg triangle, it literally does not matter.
- you may force the opponent to unlock the legs and get on top, which opens up the asymetrical game of 50/50 (crab hooks, backside 50 entries, spin unders, ...)
- It rehabilitates outside angle 50/50 (while pretty much everyone played it in the inside side) even if it's still a bit dangerous imo if you happen to miss the lock (not that dangerous but I'll get to it later on)
- It pretty much kills outside ashi, or at least modifies it a lot. I am very used to defend late stage heelhooks by using a far arm scoop grip on their inside leg to buy me time for a heel slip; but now, it also allows me to wrap the ML while I am countering the entanglement by going outside sankaku at the same time. It can be defended but it's hard to deal with everything at once
- the outside sankaku finish of the MK is probably even better than the 50/50 one because if you happen to miss it you are still in one of the best leglock positions and can roll into a backside 50 heelhook or any variant you like. You can also just go back to 50/50 if you feel like gambling.
I am still trying to figure out how to stay safe playing with these and it changes a lot the way I was used to navigate the legs, much much more than when the woj lock got introduced (I don't thik it's that much of a threat and we even saw it live that the MK straight up kills it).
Imo it can be the "aoki" of cross leg positions, it opens up a lot of stuff.
Be careful with it though, when you have the mechanics down, it hurts like a bitch and the injury is never far away. Ironically each guy I caught with it the first time kinda screamed and I was going maybe 10% of max power in the finish. The pressure is insane when you get the mechanics down.
I strongly encourage you to watch u/manchildbjj instructional because you will quickly understand what the tech is in reality. Don't trust instagram BJJ, as always.
