Re: Jack Johnson- Jim Johnson was a 10 rounder.
Well, if McVey's the one with hair, then Jim Johnson is actually slightly shorter. And McVey's usually listed as 5'10, that makes Jim Johnson about 5'9.
There's about a six inch discrepancy between what Johnson appears to be, and what he's listed as.
Maybe there were two fighters using "Battling Jim Johnson" as a name. Even the three pictures on the cyberboxingzone site look like they might well be of two different men.
