Does Sonny Liston Still hold the record for biggest fist?

[Cleon]

Ive seen him measured at 14 1/2 but not 15. 15" is one hell of a fist though!

15" is massive

Yeah it's no wonder he clubbed Patterson down twice the way he did.

True its a huge fist
But the size of your fist does not necessarily mean you have big power
