Well in a way Cromartie is correct. Both teams made big news with off-season acquisitions which led many in the media to crown them champions before a single game had been played. As a result both will scrutinized, and have a big target on their backs as many will root for them to fail.
Sadly for Cromartie the two teams are also similar in the fact that they both have only one championship to go along with a lot of disappointment. The Heat has an all-time winning percentage of .486 which ranks 20th in the NBA; the Jets' .455 winning percentage is 26th out of 32 NFL teams.
The Heat's 14 playoff appearances in 22 years sounds pretty good - until you consider so many teams make the playoffs in the NBA that it is not unusual for a team with a losing record to advance to the post-season. The Heat have lost in the first round of the playoffs nine of those 14 times - including three times after they had won their division.
Not sure that is something I would aspire to - until you look at the Jets' history. In fifty years they have won just four division titles. Two of them most fans today weren't even alive to witness, under Weeb Ewbank in the sixties. There was also one under Parcells twelve years ago, and another under Herm Edwards in 2002 which may as well have an asterisk next to it, as they won a 3-way tiebreaker with Dolphins and Pats, all of whom had identical 9-7 records. Things have been on the upswing for the Jets in recent years though. After just eight winning seasons in their first 37 years, the Jets have nine in the 13 years since Parcells arrived (though most of those winning seasons are of the 9-7 variety.)
So if Cromartie says or wants the Jets to be the Miami Heat - okay, whatever. Interesting that he thought of them rather than the Lakers, or even the Celtics though.
