#1 Ric Flair

Ric Flair is arguably the greatest professional wrestler of all time, and he has never been in the main event of WrestleMania. Even just saying it sounds like a crime.
Hulk Hogan was the biggest WWE star of the 1980's, and probably all of wrestling. Ric Flair was the biggest star of the 80's of the rival, NWA. Nobody ever thought it would happen, but in 1991, Flair left the NWA after a major fall out with boss Jim Herd and signed with the WWE, and suddenly the biggest dream match in all of the wrestling was about to become a reality... until it didn't.
WWE did indeed have plans for the match even teasing it with stare downs between the two on television. So why didn't the ultimate dream match happen?...
In early 1992, WWE's live event attendance was getting pretty small and Vince McMahon decided to try bringing it up by booking a tour featuring Hogan vs Flair in the main event of each night. Surprisingly, this did little to help attendance figures.
WWE then got cold feet with the match happening as the main event of WrestleMania and scrapped it.
Instead, we got Flair vs Randy Savage and Hulk Hogan vs Sid Justice. This was just wrong. It wasn't a total loss as Flair vs Savage was a great match, but Hogan vs Sid wasn't and no one will ever convince me that Hogan vs Flair was not the right main event.
I really don't know how WWE thought that Hogan vs Sid would pull in a better number than Hogan vs Flair. And if not Hogan and Flair, well Flair vs Savage was such a great WWE Championship match, that it deserved to end the show far more than Hogan getting a DQ win over Sid.
