IMO Hardys stand up is not overrated. It's solid. And he would KO Nate badly. Nate is dropping back down by the way.
If it were Nick vs Hardy, Nick all the way. Hardy is too big and strong for Nate. Nate would have a hard time getting it to the ground. Yeah Hardys tdd isn't the best (but who doesn't gsp make look like a fool?) but it's good enough for Nate. Nate likes to scrap and he'd stand with Hardy which wouldn't be wise.
