Typically, when people look at a grappling art, they're looking at how well you can win the fight once you're on the ground. Maybe your main sport is the grappling art, in which case the submission or pin is how you get the win. Or you train the art to train your ground game, in which case once it goes down you want the submission. I'm looking at it from the perspective of someone who's primary is striking, and if I go down I'd like to create space and get back to my feet (or vice versa). My thoughts on this are that wrestling, judo, and BJJ all have different advantages towards this. I took wrestling 20 years ago, and I remember training escapes. BJJ I know seeks to control space, i.e. by creating space and filling it. Do the concepts apply to creating space and then using that space? Or what about Judo. I hear they tend to be more explosive, where BJJ tends to be more methodical. If your goal was to use the grappling skills to escape the grapple and get back to your feet, which grappling art would you choose?
