The real answer is this will lead to more games and more TV money. The owners have realized they can keep squeezing this goose because people love football. Wonder how far back this would push the Super Bowl into February.
It really just depends on the year. If it was 16 teams, the 6-7 Jets would currently be in the AFC playoffs, and the 9 seed Cleveland Browns would be the first team out right on their heels. Most of the league would still be in the hunt at this point.
