That's not how it's been defined by much of the media though. People have been painting the picture that parity=mediocirity=everybody goes 7-9 or 9-7. The NFL is set-up so that any team can recover from being horrible and win big in a short amount of time. You can suck every year if you are run by incompetent morons, Detroit. And I think that's a very good thing for a sport. I haven't really heard that definition of parity, but if that's what they're pushing, it's wrong. Parity means terrible/mediocre teams can improve quickly (SF, Denver, Cincy) and good teams can collapse (Ten, Dal?). The NFL does have parity this year. Parity technically means similar. In reference to sports, it generally is used to denote all teams are similar, there are no great or awful teams. In the NFL, that is not the case year to year. Overall, there is a general similarity in most of the teams, aside from the most outstanding (NE) or the most disappointing (Detroit).
