Round One- Middleweight Round Two- Light Heavyweight Round Three- Heavyweight Personally I think Greb takes round one but two and three go to Charles.
I don't know enough about Charles at middleweight but the fight would be at light heavyweight. I think Charles would win a UD in a great, great fight. Charles wasn't a natural heavyweight and neither was Greb so a fight above 180 wouldn't be neither man at his best
The only relevant reference I can think of here is Charles' fight with a poor man's Greb in Overlin. It was early in Charles' career and he went 0-1-1 against him, so I imagine Greb would probably be the favorite there. I suppose the question is whether Charles improved enough and that his size would factor in enough to beat him at 175 and higher. I don't know...
Charles at 168lbs and 175lbs Greb at 160lbs Both men would probably be happy to conclude the 3 fights over 14 days.
Good call with the Overlin analogy. Based on the Henneberry and Dejohn footage, Ken was very much an eccentric in-and-out type of fighter, possibly similar to Greb's modus operandi.
