The way they book...they can't sell ppv buys. They have a show that over a million people watch and they can't get anyone to pay for their shows.
By the time 2 months of building to Foley wrestling was done they'd have killed any interest. This company has literally built 3 main event matches well in the history of the promotion (Jarrett/Raven, Joe/Angle 1, Joe/Angle at Lockdown) Those are the only main event matches that actually saw a noticeable bump in buys for them.
In 8 weeks Foley would be just another guy.
