Well he wouldn`t have been champ unless he caught Louis at the end of his reign, Charles would have boxed Frank`s ears off. Schmeling would have beaten Bruno also in a battle between two top 10 contenders, Bruno would have been further down the pecking order. Frank would have had a career like the masive Buddy Baer who would have had a good fight with Frank I feel.
Deja vu He would be a good contender, but not champ. Probably would be beaten by Max Baer, then given a shot at Louis, lose, come back against Charles, lose, and be to old to even challenge Marciano. Would likely be retired or a gatekeeper at that point Easily would be the British champ over Savold tho
