The 7 most personal grudges in history

John Cena vs. The Rock

 

 The Rock and Cena was based in a deep-seeded ill will that went far beyond trend-worthy jabs. in 2008 in which Cena accused The Rock of being disingenuous about loving WWE and sports-entertainment. In turn, The Rock shot back at Cena, suggesting the hustle/loyalty/respect proponent was only in WWE for the money.
