Foster moves up to challenge Charles and Walcott for the HW title. Is it a bridge too far for Foster like it was in real life when he challenged for the HW title?
I don't think that Foster would have been particularly successful in any heavyweight era. At least not after the lower limit was moved up to 175lbs.
Charles as Lt Heavy, could beat heavies. Foster couldn't. Walcott was a true heavy, so Foster would fail there too.
Doesn't matter what weight Charles and Foster fight at. It will always be a competitive bout but I give Charles a slight edge. I doubt Foster could handle the power of Walcott so that's an easy pick to make.
