Personally, i woulnd't want to watch him fight. IMO he was never really entertaining beyond just being a really big guy. But now the big guys are athletic. I can't think of anything he brings to the table besides size and experience. Other HW's are excellent strikers. Sylvia's not. Others are great wrestlers. Sylvia isn't. Others are good JJ guys. Sylvia isn't. What does he bring to the table?
I don't see any kind of reason to bring him back other than to be a punching bag for a new up and comer.
