He is playing with everyone. He will not come back. he retired because he had achieved everything he wanted and there was nothing further to be gained by the endless challenges of mediocre fighters. He had got more money than he will ever need and has started a family. He is sorted, sure he must have the desire to fight on, and he probably would have beaten fighters a couple of years after he retired. However the longer it goes the harder it is to comeback and there is nothing out there that would bring him out of retirement. Nothing.
