I know everyone is dead set on Cena/'Taker for 'Mania 30, which for todays product is probably a likely scenario and one I'm sure the WWE will try and do next year because it makes the most sense to fixate Cena as a legend in WWE lore. Also, the rumored Brock/Rock matchup.
But, is the better selling match one that should have taken place years ago at 'Mania but never did. Since there is no chance in hell we get Austin/'Taker which to me would have been the marquee accomplishment for 'Taker streak. To me the match that would have the greatest success and truly sell 'Mania alone is Rock vs 'Taker.
Outside of HHH, HBK and Austin, these two are the only remnants left from the Monday Night Wars that could actually have a chance of facing each other and IMO, it is the match 'Taker would need to solidify his streak because the only two he has defeated on the 'Mount Rushmore' (outside of Taker-HBK, HHH, Austin, Rock) of the Attitude Era is HHH and HBK.
I ask you, which would be the better match for 'Taker to retire on (taken he actually retires next year), versus Rock or Cena?
