If the Jets were 2 games ahead of Miami and the Dolphins needed them to choke in order to clinch, it would matter. The facts are the Dolphins didn't need the Jets to choke for either of their division titles. The 00 Jets never had a better record the last 7 games of the season. Going into week 17 Miami didn't need to rely on any other team losing (that they did not play) to win the division. The 02 Jets were 2 games behind Miami with 2 games left to play. The Jets had nothing to do with Miami losing the final 2 games. The 08 Jets were tied at 9-5 with a game against each other still left. Miami had everything to do with the Jets loss in week 17 since they were the team that beat them. That was not the case with the 02 Jets division title.
4 playoff wins in 2 seasons doesn't change the previous 8 years of mediocrity.
