Who's in Charge: Superstars Questions

[thedamndest]

Tiffany just made a match for Superstars between Tyson/Natalya and Finlay/Hornswoggle, so apparently Superstars is the "Ship Your Crappy Tag Matches" show. Smackdown gets shafted here, as the threat of having to appear on Superstars doesn't materialize until an entire week, so if you're going to make a match for two competitors you might as well make it for next week's episode of Smackdown and increase your own Smackdown ratings.

Kayfabe-wise, are all GMs on hand to replace superstars in case card changes must be made, or can those kinds of changes be done over the phone? Should there be some kind of "authority figure" to ensure that all superstars are showing up to the arena on time and competing in their matches in the absence of a GM?

And of course the question that we all need answered: Is Superstars canon? I submit that it is not canon unless it contains Maryse, who is hot.
