I think this is the best perspective. It's the one thing we *know* is going to work out.
He won't provide much in terms of in-ring work, even if he had a late-stage revival with some enjoyable matches. He's 49, y'know? While he might be the best giant in wrestling, age and wear and tear must have taken their toll on him. I would be down for a match against Shaq just for the fuckery, but I don't see him doing much more, sadly.
Is he going to provide great insight on commentary? I don't recall him ever being put on the guest spot at WWE, too.
