FRISCO - Cowboys third-string quarterback Mark Sanchez said Wednesday that he was frustrated with his play in Dallas' 27-13 loss last Sunday at Philadelphia. Sanchez struggled and threw two interceptions in his first extended playing time of the season. He got the opportunity so the Cowboys could protect Dak Prescott and Tony Romo for the playoffs. Sanchez declined to talk to reporters after the game.

"After the game, obviously I'm a competitor," the eighth-year veteran said. "I want to go out there and win and play well. So I was pissed. ...But listen, you get 24 hours to be upset or be excited about it. At the end of the day, it's never as bad or as good as you think. A lot of good things in there. ...Then a couple of things we want to change, and that's what we'll do."

Sanchez didn't help himself make a case if the Cowboys are looking for a backup quarterback next season. But he has been a mentor to Prescott this season, sharing his own experiences of starting as a rookie for the New York Jets, who advanced to the AFC championship game in his first two seasons in 2009 and 2010.

The Cowboys brought on Sanchez just before the season started after he was cut by Denver. The quarterback room consists of a unique mix of players who are all in different roles than they would've expected in 2016, including Romo serving as a backup.

"So sometimes the reality doesn't match your expectations," Sanchez said. "But OK, now what? You know, we have a saying around here: 'The only thing that matters is what you do now.' And how are you going to help the guys around you? How are you going to help the team win? ...That's what we've been trying to do and everybody has kind of accepted their role as easy or as tough as it maybe, and that's the way it goes."
