9. Steve Austin
The man described by Vince McMahon as "the most demanding star I have ever worked with" has to make this list. To be fair to Austin, he always gave his absolute best to McMahon, so was justified in demanding the best treatment back. If anyone could be entitled to having an ego, it was the Rattle Snake: it was he after all who carried the WWF to new heights of commercial success. He sold tickets, pay per views, merchandise and media in a way that made him McMahon's biggest attraction ever. Was he bigger than Hogan? Absolutely. Despite his deserved spot as an all time great, there is no doubt that ego did damage Austin's career at certain points. Even best friend Jim Ross accused Austin of "thinking he was bigger than the business" in the 2002 WWF Confidential DVD. That DVD feature was based off the fact that Austin had gone AWOL and quit the WWF in 2002 because he disagreed with creative. As Ross and McMahon pointed out, you may disagree with creative but you still have a job to do and a responsibility to the paying audience. Austin had shown a lack of care for that notion - he simply didn't show up to work and didn't go back, having been upset that Vince wanted him to put Brock Lesnar over on TV in a match with no build up. As far as Austin was concerned he was too big to do that, and as McMahon states - "he decided to take his ball and go home".
