Bring back Paul London.
No, I'm not a London mark, but that kid had talent. Plus, he is bilingual which could help make for an interesting angle for him. He could come in as a "Lucha Libre" style wrestler, only to unmask himself to reveal who he actually is. I think feuding with Alberto Del Rio would be great for him to establish himself in the WWE. An upset of the ages vs Alberto Del Rio. I'm not certain why they ever go rid of that guy in the first place.
