John Cena's character is normally protrayed as a underdog (though everybody knows he isn't). Like, when he goes into a match, the odds are stacked against him, and WWE use that, except CM Punk is saying that Cena's not a underdog anymore, he's the favourite. I know nothing about baseball, but I'm going to take a guess and say that the New York Yankees are like the best team, or something, and that they're normally the favourite going into games. BQ - Cena is from Boston. Even I know that he must hate the Yankees.
