James Toney may not be a top fighter any more but I think he lasts a long time vs damn near anyone, solid defense and a hell of a chin still go a long way.

Hopkins is very cagey, he is difficult to catch clean and he fouls often, but vs ANY top heavyweights that can punch he'd get KO'd

Tarver is a fight I'd actually like to see because I hate that dude and would like to see him KO'd
