This link here takes you to a house show report on the Observer for 12.05.2004 Smackdown house show at Madison Square Garden. Pay close attention to the first line of the report where it shows the attendance. Isn't there something a little... odd about that, considering it's an MSG show?
6,000 to 6,500 for a Sunday afternoon house show isn't an awful figure in the current marketplace. This isn't the old days of MSG where the McMahon's would bang the place out with 22,000 plus every month. If they were doing that, they would book MSG every month for a house show, rather than just once every six months.
I like all of these people but I don't see any of these as a big deal. You make it seem like there is a big exodus of unhappy people but D'Lo is going to a bigger federation that is going to let him wrestle.
