Anything that WWE decides to push as being worth to watch. If they wanted, they could sell Dolph Ziggler v KungFunaki v Jack Swagger for the Undisputed Championship. It would take a while, but it would definitely sell.
On the other hand though, NOTHING they can do would put butts in the seats like a midcard match on an house show 10 or 20 years ago would have.
Pretty contradictory reply eh?
I know that over the last several months I've lost a lot of things, and one of them has been my smile ... and I have to find my smile because somewhere along the line I lost it and I don't care if people want to make fun of me because I'm an emotional guy...
