On that and Choynski, Griffin, Munroe and Sharkey, basically the biggest punchers the era could offer, you have to say he was one of the most durable heavies ever...
For a long time I too believed Jeffries chin was unproven because he did not take the shots of big heavyweights.
However after reading about the punishment that Fitz inflicted on Ruhlin,punishment that threatened his life and left him bedridden for some time, and perusing the accounts of the shots that Jeffries shipped in his second fight with Fitz , smashing his face to bits but leaving him still standing. I put Jeffries in the top echelon of durable champions chin wise.
