Greatest fighter per division who were relatively small for their division?

Bob Moha at LHW deserves a mention. 5 ft 5.

 

Not remotely saying he was the greatest small man in divisional history but at 5’4 and a middleweight James Hard Rock Green was a midget.

 

Wow.

 

Has Dwight Qawi been mentioned yet? In terms of height, at 5’6 1/2 that’s a very short light heavy, a miniature cruiser and a dwarfish heavyweight.

Impressive when you consider he’s a top 20-25 light heavy all time, arguably a top 10 cruiser (H2H at least) and a decent enough heavyweight.

 

Yes, Greb was actually a "big" middleweight during his championship years.
