How Good was Norton's Chin?

[SenorPipino]

I'm sure by the early 70's, Team Norton was wary of putting its fighter in with anyone who could whack. Too much evidence that Norton's chin was suspect.
When did Eddie Futch begin training Norton? Did his arrival help mask any weakness in Norton's chin?
Norton did fight a lot of smallish heavies, but to be fair, in the late 60's and early 70s, heavyweights over 210 lbs. were considered big. Overall, they didn't have the size of today's combatants.

Interesting that Futch was fired just a few months before Norton fought Foreman for the heavyweight title.
The fight must have been signed by January 1974 for the March 1974 battle, so it's strange they would dismiss Futch with the biggest fight of Norton's career looming.
It couldn't have helped Norton's preparation for the match in Caracas.

Are Pipino and Duce the same person?

They both seem eager to swallow a lot of unverified crap.
