'jones' and 'goat' are mutually exclusive, they don't go together. on paper his resume is incomparable but you cannot ignore the huge asterisk towering over it, there's no way to do that and sound credible. it almost doesn't even make sense to have the discussion.
but no, beating the GOAT doesn't make you GOAT, all by itself. if jones' run had been legit, then losing once to poatan doesn't just automatically transfer over that whole epic legacy all by itself. he'd have to defend for years on top of that to make it stick.
