If you could change the main event of any past WrestleMania. Which Mania would it be and what would be the match. An explanation for the match would be good too. WrestleMania 29 - Rock vs Cena vs Punk: At the time Rock, Cena and Punk were highly active at the same time. You would think after the #1 Contenders match on RAW that Cena and Punk would feud on about it into WrestleMania 29. Instead Punk got into a promo on Old School RAW with Big Slow, Sheamus and Randy Orton leading to a pretty ok match The Undertaker. Still it would've been in good IMO.
