1) Shawn Michaels - Simply put the greatest of All-Time, he can elevate almost anyone and have a great match with just about anyone. His matches are legendary and probably has more amazing ones than any other wrestler in history.
2) Bret Hart - "The Excellence Of Execution" indeed. He could have a match with anyone and make it great or exciting. Doink, 1-2-3 Kid, Hakushi, The Mountie, Bam Bam, Razor, Bob Backlund, Jerry Lawler, Isaac Yankem, etc etc.
Putting guys over is a big part of the business and Bret knew how to do that better than anyone. The only reason I took Diesel seriously was because of Bret Hart, arguably his best matches were his series with the Hitman. He'd be number 1, except he always messed up on the mic. If with his only flaw, it's still hard to put him #2.
3) Owen Hart - The Blue Blazer, The Rocket, The King Of Harts, 2 Time Slammy Award Winning, The Black Hart, The Sole Survivor........IMO he was better than Bret Hart, but we never got to know that. He was almost always overshadowed by another match on the card, because he didn't main event. They never let him have his chance at the top (which was a huge mistake) and I think people forget how good he really was. He had more charisma, a better look, more agility, better mic skills, and a greater arsenal of maneuvers than his brother. He truly was the "King Of Harts." My favorite wrestler of all-time since I was a kid.
4) Mr. Perfect - What a shame he never held the World Title. He had it all, he was a gamer, had a great look and entrance, was a master in the ring. Truly unbelievable to watch.
5) Kurt Angle - "Oh, it's true, it's DAMN true." If their was a clone of Bret Hart in the ring, it would be Kurt Angle. His timing was flawless. He was a great face, a better heel, and an anti-hero to boot. You believed everything he did in the ring, plus IMO he had one of the greatest finishers of All-Time, The Angle Slam. Simple, but at times devastating.
6) Triple H - He is the total package. I hear a lot of people say he didn't put guys over......BULLSHIT. He put over more guys than anyone since Bret Hart. "Hardcore" Holly, Jeff Hardy, Batista, Kane, Henry Godwinn, Goldust, Taka Michinoku, and a ton of others. He gave these guys big pushes, what they did with those pushes is not his fault.
7) The British Bulldog - Another legend who doesn't get the credit he deserves. He could really move in the ring and had an intensity only comparable to Kurt Angle. His matches with Bret and Shawn and Owen are some of the greatest of All-Time.
8) Randy Orton - The Viper is unstoppable. Not since Angle have I seen someone with as much talent as him. He does everything well, has the right look, theme and approach. In such a short career he has had some remarkable matches, achieved some incredible goals, and proven that he is the future of this business.
9) The Undertaker - The Phenom is something to behold, he has been and always will be a marvel in the ring. The greatest big man in the business, no contest. For a guys his size to do some of the things he does? It's remarkable. Leaping planchas over the top, walking the ropes, taking insane bumps that not many his age take. You may ask why so low on the totem pole here? Well I ranked him this low only because in his long career (AND THIS IS NOT HIS FAULT BTW) he hasn't had as many great matches as all those before him. I Repeat, this is not his fault. Not his fault that for years he had to wrestle crappy big men, like King Kong Bundy, Mabel, Hulk Hogan, Mr. Hughes, Kama Mustafa, Giant Gonzalez, A-Train, Test, Big Show (before he got his shit together), etc etc etc. It's unfortunate, but in the first half of his career he didn't have many great matches, it wasn't until his feud with Mankind where his abilities could really be showcased.
10) Chris Jericho - Y2J is a legend in his own time. Night in and Night out he has some of the greatest matches. He truly has SAVED the WWE. Before he came back WWE was going to shit and as soon as he did come back it became interesting for me again. His mic skills are unmatched, his technique is flawless and he has some incredible and unique finishers. Very rarely do you see a bad Jericho match.......just this past Monday he had the only good match on the show. That's the level of Jericho's ability. Not to mention he probably has the greatest debut in WWE history.
Honorable mentions:
Chris Benoit - In the ring, one of the best. On the mic, he was mediocre at best and didn't have much going for him in terms of personality. Actually I thought his mic skills were better than people made them out to be, I thought they were better than Bret Harts, but Benoit didn't have the great catch phrases or personality of the Hitman.
Bam Bam Bigelow - If Undertaker is the greatest big man, than he is a close 2. So agile, moonsaults, flying headbutts, inzaguris, he was unreal. He took great bumps, had a fierce look and was extremely quick for his size. He could move like a cruiserwieght and unload the power of a heavyweight.
A classic Bam Bam moment: Tatanka starts dancing like he did, Bam Bam's hitting him and nothing is working. Finally Bam Bam does a inzaguri to the side Tatankas head while tatankas in motion and sends him to the mat. He did great little things like that, very misused. He would've made a great IC or World Champion.
