20. John Cena vs. The Rock
A war of words began between these great pro wrestlers. Cena is quoted from a 2007 interview stating he doesnâ€™t feel that The Rock gives back enough to the WWE. Cena goes on to say that his rare appearances at events do nothing to promote the industry. The Rock shot back claiming Cena only wrestles for the money. Eventually, they put their differences aside and came together for WrestleMania 29.
