It was by no means a guarantee that WM 3 was going to be financial success. Same with WM 1.
And, contrary to what you keep saying elsewhere, Dave does not hate Monsoon. He disliked his commentary style, but that was it. It was not, and never was, personal.
Straight from Dave:
I did jump to conclusions about Dave hating Monsoon at NMB but it just seems he NEVER lets an opportunity go by to say how bad he was. I mean he was talking about shows over 20 years ago and he still can't let it go. It just seems he goes out of his way to criticize him when Monsoon really isn't even the main subject.
