For every team in the NFL, focusing on your own division is the best way to identify what you need to do for your team. Winning your division guarantees you a home playoff game even if you have a better record than the Wild Card team you are hosting.
For the AFC North, it is really about surviving the best division in football more than anything else. Last year, the Cleveland Browns, Baltimore Ravens and Pittsburgh Steelers all made the playoffs but only the Ravens seemed to have a chance to go far due to quarterback play on the other two teams.
