It is abysmal the shape the average American man is in. Chances are, any given American man is fighting 3 or 4 weight classes down from his "walk around weight". Even many athletes in other sports carry around a decent amount of muscle and heft more than they would be ideal fighting at and could go down 2 or 3 weight classes from "walk around weight".
Not to mention the whole term "walk around weight" is vague: some men walk around in tip top shape; others...don't. So, "walk around weight" weight could mean on one end of the spectrum, a man in tip top fighting shape but pre-water cut...while on the other hand it could be a Paddy Pimblett type dude that does mukbangs.
Also, you have to ask yourself this: how do you feel about fighting men that are bigger than you? Alot of men - including high level fighters - are very comfortable being the larger man, but are clearly out of their element being the smaller man. If you are one of those men that is uncomfortable being the smaller man, then the option of cutting as much weight as possible is there for you, but, at the expense of depleting yourself and making your brain more susceptible to being knocked out. And then, on the other hand you have guys like Azamat Murzakanov who could make WW and maybe even LW if he wanted to, but is knocking out LHWs and is willing to fight at HW on a moments notice (he did take a HW fight on short notice but it go scrapped).
