Starting at the Royal Rumble pay-per-view event, WWE began airing videos for John Cena and The Rock detailing their lives leading up to their match at WrestleMania 28 on April 1. Cena's can be seen here and Rock's is above.
As Stephanie McMahon has mentioned, they're going for a "Team Edward vs. Team Jacob" type of build, where they present fans with all the information they need to know on both guys and everyone chooses a side. I can't say I blame them and really, it's one of the only ways to a market a babyface vs. babyface match.
More great work from the WWE production team and the train headed for Miami keeps chugging along.
