"now how in the Hell did Undertaker get that high? "
Well, if you go by storylines, he did hold the title for quite a while this past year, and was made to look quite strong.
I mean, I can think of more deserving people of such a high spot from a smart perspective, but consider if your main source of info is what you see on RAW and Smack!Down: here's this giant texan on a bike that's held the World belt for longer than anyone since Jericho, and who really cares about Jericho? This Taker guy is mean looking, beats a lot of people cleanly, and JR tells me he's been beating up everybody for over ten years. Hey, look, there's a wrestling magazine that lists the top five hundred wrestlers. WWE has that many people? Wow...yep, there's Taker, but why isn't he at #1?
The only one that kinda perturbs me is Rocky, since hes had a distinct LACK of wrestling in the past year. Don't get me wrong, hes still good, but hes not done much actual wrestling. At least that I've seen.
Marty doesn't need surgery. This is a great day. I almost feel like I can say, I don't care that the Steelers lost. Again.
It's a different time and generally speaking I don't think comparing any of the numbers you've selected across such hugely different and displaced eras lends much insight into the wrestlers themselves or the success of their reigns as champ.
