TNA would beat SD, I am sure of it.. hell I don't even get Smackdown where I live.
If TNA was to go up against SD that might be interesting coz it could effectivly chop a leg off WWE. Guys like Jericho, Batista, Taker wont want to be on a show that is hardly watched would they?
Even i would would think a live TNA weekly broadcast could serious hurt SD and WWE as it would take a much longer road ro knock RAW off IMO. Maybe a 6 month period on Friday and see how it goes. But then maybe they might look like they aren't up for the challenge.... All interesting thoughts.
