It's sad to see the weight shaming of Chris Hero. It's obvious he has struggled with this issue his whole life. He has alluded to as much.
As a (almost former) fat guy, I would say sure. But when you make your profession one that requires you to be naked and fit, I think it's okay to comment on someone being super out of shape.
In wrestling you either need to go way over the top with it and become Rikishi or be muscular, that's your options.
