A big trend these days in BJJ is "Ecological" training, basically using games to specifically train certain positions or techniques. It comes in multiple forms, but in general it focuses more on live work rather than drilling, the theory being that you learn better that way.
An example is if you are training Triangles, the game would be that you are only allowed to strangle with your legs. Or if you're training back takes, the game would be no submissions and taking the back means you win. That's pretty simple, but some schools have gone really far with it to the point of never drilling at all.
What are your thoughts on this game-based training? I personally enjoy it, but my school does still drill a little bit even after we started trying out the games and I think that blend is a good way to do things.
I think it is very misunderstood by people that haven't actually experienced it.
Simply "Only use triangles" is not really ecological approach, at least not beginner friendly as you have to have the context of what a triangle choke is in order to do a drill like that.
Eco or CLA "games" are usually much narrower in focus and designed to get a specific result. With coaching on how to get that result mixed in.
Designing a CLA based approach to learning jiu-jitsu probably takes a much deeper understanding of jiu-jitsu then teaching a move of the day curriculum.
I do think both are needed to really get the best results. Different people learn in different ways, and a "without resistance" walk through can help people get the mechanics and motions of something down, especially more complex motions.
But in general static drilling can help you learn mechanics, CLA drills help you get good at doing them against another person
