The Cowboys qualified for the playoffs after the 2003, 2006, 2007 and 2009 seasons. Their playoff record during that period was 1-4.
Since the Dallas Mavericks were established in 1980, they have made it to the playoffs 20 times.
The Cowboys have made the playoffs a total of 30 times from 1966 to 2009.
Right now the answer is a wash, as the Cowboys made the playoffs in 2009 and won a game, but the Titans have shown consistency in winning to a greater extent than the Cowboys over the last four seasons.
As of 2007, the Giants have made the playoffs in three consecutive seasons.
The Chicago Bulls have made the playoffs 29 out of their 44 seasons.
The record belongs "officially" to the 2003-2004 New England Patriots with 21... including playoffs making them the most consecutive. Indy Colts 2008-2009 had 23 regular season wins. The previous poster said the New England record included pre-season games. In fact neither teams records include preseason games. Both lost preseason games during the "streaks." The difference being that the Patriots record is considered the "official NFL record" because it includes playoffs games.
Dallas Cowboys
