I definitely see this being a "filler" PPV...granted they have been giving it a decent build-up with the main event focus, nothing is screaming greatness yet.
Main Event of Eddie & JBL really needs to have some type of gimmick. They could call it a Texas Death Strap match (basically a gimmicked strap match) and I think it would add something to the match. Only real problem with that would be Eddie'd be unable to hit that frog splash.
US Title Match of John Cena & Rene Dupree could prove to be pretty decent. In order to establish that, I want to see Dupree actually get some in on Cena...maybe during a future cafe segment, have him invite Cena out & while has back is turned, crack a wine bottle over it. Dupree has great charisma but has been made to look like a fool with Austin & Cena thus far.
Undertaker vs. Booker T : Could this be booked as Undertaker calling Smackdown his yard & Booker is disrespecting it? Possibly, but given that Taker hasn't been on the mic since waay pre-Wrestlemania, I don't know if he'll still carry that or if he'll be using the deadman lingo. Either way, Booker is looking hot coming off the RVD fued & so a loss to Undertaker won't bury him.
Outside of these three matches, I'm not sure what to expect. I'd imagine Mordecai will make his in-ring debut. WWE Tag Team Title defense between Rico/Haas & the Dudleys seems to be in order...good lord I hope the Dudleys take it. The spot with Rico & Rikishi was funny though...
This leaves a lot of guys out there. RVD, Mark Jindrak, Chavo, Show, etc...
