Re: WM18 Should have been Hogan vs Austin...
Rock never refused to work with Shawn (I think). He said back in 99 that he never had interest in working with him but I don't think he was ever offered a Michaels match and refused it.
It's been said here that Michaels disrespected Rock's mom before.
I believe the match he refused was WM 19. They wanted him to face Michaels he wanted Austin.
