1. Hulk Hogan. Very little that can be said about the guy that people have not already brought up. I liked him as a kid (though not as much as many others) and I have a mix of spiteful disdain and pity for him now. But in terms of his mark on being great at what he did, he was. The man drew like nobody else, cut promos all his own, and more than almost anyone else in history he OWNED his character. That's important. Terry Bollea WAS Hulk Hogan - the character came to life, then became larger than.
2. Ric Flair. Yes, the man drew. He was a fantastic heel and put on some long and thrilling matches. To this day he stands as one of the most legendary promo men ever to step in the ring. He maintained ring-worthy athletic condition well into his 50's. He is one of the men around whom the business was built, and he was fantastic at it. Anybody who tries convincing me or anyone else that Flair wasn't great for whatever reason is full of shit. When I watched Wrestlemania at my usual bad this year and the ENTIRE place, even with some non-wrestling fans in attendance, stand and cheer - you cannot tell me he didn't have an impact as one of the greatest ever.
3. Shawn Michaels. It took much deliberation to put him on this list, but the facts stand for themselves. From his days in the AWA, Shawn worked is ass off putting on fantastic matches in front of small crowds. He didn't care. Michaels went out and didn't just work his matches - he had FUN doing so. He loved it. With so many people talking about wrestling as a business, Shawn shows his passion for it. Come on, how many pro athletes get hurt and just collect checks until they retire? Shawn came back from a back injury that would end any other pro athletes career and still performs at the highest level. He has "IT." He draws as a face or a heel, and he always gives EVERYTHING he has to the crowd and to his opponent.
4. Big Van Vader. Hands down, Leon White goes on my top 5 list. And it was either him or Andre, but when push comes to shove, Vader is the greatest Superheavyweight EVER to grace the ring. This man had it all. He was more powerful than even a lot of 450-pounders were. He was as agile as a 250-pounder, doing splashes, drop kicks, moonsaults, etc. He used the ring as well as anyone I've ever seen. If you didn't give EVERYTHING you had in the ring, he worked stiff and brutalized you to make sure you ALWAYS gave your all. He was well versed in high impact and power-based offense as well as technical mat wrestling (see: Japan vs Antonio Inoki). Despite the stereotypes about SHW's, Vader was as "in shape" as anyone ever was, putting on longer than average matches and willing 3- or 4-match tournaments in Japan. When Ric Fair hit WWF in the early 90's, Vader was the man who practically carried WCW as the top heel vs Sting and Simmons. This man only recently started getting the IWC respect he deserves in the WZ Tournament, and I'll be damned if I'll allow everyone to forget it.
5. Randy Savage. Tough choice here at #5. I understand people tossing The Undertaker on the list, because of his iconic loyalty to the WWF/E and its fans. But man, Savage was intense, athletic, and worked equally well as a face and as a heel. Here's a stat I looked up and developed myself - Only two men in Wrestlemania history have headlined back to back Wrestlemanias as a face at one and a heel at the other. Randy Savage at Wrestlemanias 4 and 5, and Shawn Michaels at Wrestlemanias 11 and 12. Savage worked equally well as a face or a heel, and is responsible for some of the greatest Wrestlemania Matches of all time: vs Steamboat (3), vs Warrior (7), vs Flair (8). He was powerful, he was agile, he could hit the top rope, he could hit the mat, and MAN could he ever cut a promo.
That is my short list of 5, though ask me again in 3 months and I'm sure I'll change something around. A short list without Austin is hard for me to look at, but NO I will not remove Vader.
