Should Roy Jones Jr. fight Antonio Tarver for the 4th time?

Roy Jones Jr had a great career and is certain to be a first ballot Hall of Famer. He has had a relatively safe career with few battle scars until his second fight with Antonio Tarver. Since then he has rapidly declined and has absorbed way too much punishment. I understand the will of the fighter to want to fight on and overcome adversity but in reality there are no fights out there for him that will do him more good than bad. As a fan of Jones Jr. I would really like him to retire. As for Tarver, he has accomplished a lot in the sport of boxing but I can't see him making a significant impact at heavyweight and another fight with Jones Jr. would do nothing to improve either fighter's career. I think that his best move was transferring to the broadcast position like Roy has done. He too should retire. I wish them both well and hope they are financially set or are working toward that stability. They should definitely not fight a fourth time.
