Oooof. I think that Johnson's technical advantages, advantages in combination punching, would tell. Because I don't think that Johnson has ever showed any "tenderness" of any kind and could probably survive the Norfolk maul. The question, I think, is could Norfolk physically dominate Johnson? And I think the answer is no. Johnson was strong and tough. So Johnson shines enough to take a decision.
It has to be noted that Norfolk was pretty effective against guys like Miske, who were technicians with good power to back it up. Still hard to say!
Johnson, besides being a technical whiz, was a strong man too and I thik he wouldn't be dominated by Norfolk....and he would decision Kid Norfolk.
