Owner Jerry Jones has repeatedly said the Cowboys are just getting started with Jason Garrett as their head coach.
For the core group of veteran players like Tony Romo, Jason Witten and DeMarcus Ware, losing yet another season finale with a playoff spot on the line is another chance lost.
The Cowboys finished 8-8 in Garrett's first full season.
Jones says Dallas has to take advantage of the talent and experience of players like Romo and Witten, who aren't going to be around forever.
Linebacker Sean Lee said Monday that the Cowboys showed flashes of being a very good team but were inconsistent.
Dallas lost four of its last five games, including 31-14 Sunday night at the New York Giants with the NFC East title on the line.
