Well, that's the problem with wrestling today. There are too many PPVs between WWE and TNA. Throw in competition from UFC, and it's just like they're splitting up the same pie too many ways. There's only so many PPV buy dollars to go around.
That's why I laugh when people say WWE should bring back a "Clash of the Champions" type event. When they hell would they run it? Wednesday nights, in between ECW and Smackdown? Maybe find a week when there's not a PPV the following weekend? It's ridiculous.
