Oh my thumb is pretty bendy too
Troy’s talked about how people that fit certain anatomic profiles have access to doing things different ways. So I wouldn’t say your idea hasn’t caught on, or maybe better said “wasn’t on the radar”. Any positioning thing we can do is going to have some implication on how we play. It’s how all the amazing players got to where they were. They chose comfortable setups and figured out the joint/muscle combo that worked with that. I’m sure it’s chicken/egg as to if that ended up dictating their vocabulary or if the vocabulary coaxed them towards the setup that worked with it best.
