Depends how you determine freakishly huge Sonny Liston wasn't short (6 foot), but he had an almost 85'' reach. To put that in perspective I'm 6'1 and have 76''. Nikolai Valuev (7 foot) and Tyson Fury (6'9) both have an 85'' reach. So I'd say Listons was freakish for his height.
Mayweather is listed as 5'8 with a 72 inch reach. Mosley is listed as 5'9 with a 74 inch reach. Paul Williams is tall as hell, listed as 6'1 and probably a couple inches taller, but his reach listed at 82 inches (6'10).
for sure, but he is actually taller than listed, dude is probably 6.3 and his reach is comparable to foreman.
