Question for real historians - Which was the biggest size difference ending in a KO for the smaller?

Dempsey 182 Willard 256

Walker. deKuh

 

I don't know if this is the alltime record, but just recently Julius Long was knocked out by Hemi Ahio despite being 13 inches taller and 96 pounds heavier.

On September 3rd, 1892, Bob Fitzsimmons, at 160 pounds, knocked out Millard Zender, at 300 pounds, in the 1st round, in Anniston, Alabama, USA. That's a 140 pounds weight differential.

 

Wow. Just, man. Holy. Moly!

 

Had no idea Fitz ever fought in Anniston.

Did a quick bit of research: Anniston (originally Annie’s Town, named after the founder’s daughter) was an iron company town in the 1870s and before this fight became the first Alabama city lit with electricity.

Apparently in this period it got a reputation as a resort town (how I have no idea, you wouldn’t think it if you visited anytime in my lifetime … maybe just because it had electricity?) and a number of hotels cropped up.

Within a few years after this fight it got an Army camp which would later become Fort McClellan, and by WWII it was one of the largest Army bases in the U.S. It later become a major munitions depot and finally was decommissioned in the late 1990s.

For several years it hosted the Alabama Golden Gloves and fighters/trainers were able to stay on the base/campus in Quonset huts. It was pretty cool to go and affordable because of the free housing.

 

Turkey Tompson vs Ben Moroz must be in the mix.

It can happen, it's not just the size alone. I have seen smaller guys beat a taller fighter. The smaller have more balance, some taller guys are very clumsy. It is a matter of skill and desire.

 

Size should encompass height and weight.

A 6-foot-7 guy who weighs 155 pounds would not be “bigger than” a 6-foot-4, 250-pounder. He’d just be taller.

When you order a large soda, they don’t give you the same number of ounces in a taller, skinner cup than a small.
