I struggle to find a winner. I think the fight would stink it would go the distance ...but from the purists view, there would be some nice boxing.
I think the Tucker who beat Douglas and extended Tyson the distance would win a decision on the basis of his height reach and conditioning. After his hiatus In the late 80s he gained weight, got slow and was less busy in the ring. Hunter had a knack for taking advantage of fighters once they got to this point.
