Hard to say, but I don't think Greb fought a puncher and finisher close to the level of Fitz. I guess you could counter Fitz never faced a swarmer on the level of Greb, but he did beat some decent pressure fighters, including Sharkey who was decently bigger than Greb, and the style match up generally favours the puncher.
Fitz. Interestingly, it is not completely out of the question that this one could have happened. It wasnt discussed or anything, but Greb would been active or close to active around about the same time that Fitz gained recognition from the NYAC as the reigning world middleweight champion (or was it just that he was trying to gain recognition).
