Froch was the same height, had longer reach. Froch's ring weight was pushing 180 if memory serves. The things that Corbett does "faster" than Froch I would barely label as boxing. What Froch does IS boxing.
I’ve never been able to see the rationale with having matchups like these. The eras are so far apart that you’re literally talking about two different sports when you look at the vast differences in rules and circumstances
froch is SMW. corbett is fair LHW (HW at his Time). i pick corbett.. he can handle HW at his time & he can handle froch power. Froch not quick enough.
According to a report from San Fran Chronicle on the eve of the Fitz fight, Robert's weight was claimed low and Corbett's was claimed high. The reporter said consensus was that Corbett weighed 170 and no more. Froch came in the ring over 180. The difference really here is that Froch knew how to box.
I could find you half a dozen different figures for Corbett's weight. The bottom line is that we don't know, and you don't get to cherry pick the one you want. Have you actually seen footage of Froch. He had an unorthodox style that worked, but the idea that he represents some evolution in boxing technique, is laughable. He is probably the best argument that the old time style would have worked in his era!
I think Corbett is the best argument that old time style wouldn't have worked in this era! I mean, he was thought of as one of the best in his own time - but would likely have been out of his depth against even half-decent champions 100+ years later.
