This has been my position on smaller heavies from the past being put in the modern scene. We might never even know their names. They would be burned out and busted up before they were able to reach the top ranks. Marciano, for instance, had a bad back from dealing with a bunch of 180-190 pounders. How long would that back last when his average opponent was 220 and many were 240? The best strategy for the smaller heavies would be that of Jones, Jr or Spinks, a quick shot at a belt after winning those at LHW or Cruiser. And then either go back down (dangerous in itself) or retire.
