If we can bring up anecdotal evidence, i don't see non-wrestling fan friends or people at my work or whatever talking about wrestlers like I saw during the Hogan, Monday Night Wars, or Cena eras. I feel like their success right now is from doubling down on the modern WWE fans they already have and catering to their whims more (which I think are different from a lot of the people who visit this board).
Also, I feel like Undertaker belongs in that list with Foley and Austin etc. Again speaking from anecdotal evidence, I really feel like most of the people I went to school with in the 90s who didn't watch wrestling still knew who Undertaker was.
