I would like to see him some more. I think that he took to much time out of the ring however, I do not think he could beat most of the serious contenders out there. He is pretty old and he has got some improving. If he took some easier fights focusing on ground and pound defence he would have a chance but it would defanitly be a race before he would have to retire.
He has the skills but will he choose to get them back into shape is the question.
