If John Cena were to leave WWE, does that mean low ratings!?

Yes, it does mean low and terrible ratings, according to Nieslen Ratings, WWE Monday Night Raw is not #1 on cable ratings, it was beaten by Pawn Stars, iCarly, and any NBA basketball games during the NBA Playoffs but not all of them. However, John Cena is the Dale Earnhardt Jr. of Wrestling due to his popularity and he will be still popular if he goes to acting on many blockbuster movies and not some terrible-reviewed movies that he was in (The Marine, 12 Rounds, and Legendary) or at least, going to a another sport (ex. NASCAR, NFL, MLB), but can't go to NASCAR because it will cause a "popularity" rivalry with Dale Earnhardt Jr. for being the Most Popular Driver.
