You have (current game pending) three 13 win teams in Dallas, Green Bay, and Indy. Jacksonville and San Diego won 11 games. Pittsburgh, Cleveland, New York, Seattle, and possibly Tennessee have ten wins. The majority of the teams qualifying for the postseason have 10+ wins. I don't see how it makes any kind of difference whether the teams not qualifying are 7-9 or 3-13. It's when you have multiple teams hovering around the .500 mark making the playoffs that the merits of league parity really become debatable.
