I love the "any 6 wrestlers" schtick, very reminiscent of Quintet and now CJI (both BJJ competitions). However, I don't know if the format will be as adaptable to wrestling as it's been to BJJ.
Not sure how much I love the actual ruleset, but it's interesting for sure. I think once I see it in action it will make more sense.
I wish them all the best, wrestling needs a professional league (or a few), but we aren't positioned for one the way other sports are. I hope they can build something cool.
