The Cowboys have one of the most enviable quarterback situations in the NFL, with a preternaturally poised rookie and a decorated, veteran backup available if disaster strikes. The question is, what will qualify as disaster for this team, which had been speeding into the playoffs and now seems to be crawling? We hear a lot about windows for championship in the NFL, but the truth is that there is no window, there is only one season at a time. Jones and the Cowboys know that better than most -- they have suffered excruciating playoff losses, and missed the playoffs entirely, despite having one of the best quarterbacks in the league in Romo. When does the desire to pull every possible level to win another Super Bowl put Jones' hand on the lever for Romo if Prescott does not rebound?
