Not legally where? There are a lot of places in the world.No. Not legally.
Finally someone who shares my visionwouldnt be successful because it wouldnt be viewer friendly so i dont think one could exist today because no one would back it...however my ideal rules would be pride rules with elbows and 1 15 minute round, no judges or scores, if there is no KO or submission no one gets a win or loss, the fight will stand for itself no need to append some subjective footnote to it, if you want to know what happened in the fight you have to actually watch it
