One of the many things leading to the crash and burn in Dallas was the failure to have a serviceable backup at quarterback. The remainder of the season at least allows the team to try and make some informed decisions about fixing that.
The season is over for Tony Romo, which also has ended any rational hope for the Dallas Cowboys. However, there are still five games to be played. Although the team would benefit psychologically from getting some wins (and would unfortunately surrender draft position at the same time), those games will also be a time for the staff to evaluate the performance of many players on the roster to determine what, if any, role they will have in 2016.
