Jerry Jones has emphasized that the Dallas Cowboys must have a sense of urgency this year because he believes that their "window is closing" on winning a Super Bowl. This has put a lot of national media attention and pressure on his team and especially on his quarterback Tony Romo.
The Cowboys aren't the only team in the NFL whose proverbial window of opportunity is closing on them. Teams throughout the league are facing various circumstances that could eventually hurt their chances of realistically competing for a title in the near future.
Whether to fend off "Father Time" or inevitable front office intervention, these teams will need to win a title for their year to be deemed a success.
