FRISCO, Texas -- While Mark Sanchez has a new offense to learn in Dallas, the veteran quarterback sees another important element of his role in his first week as the backup with Dak Prescott preparing for the opener against the New York Giants.After all, Sanchez was a rookie starter once, too.You dont want to bombard the guy, especially as a rookie, Sanchez said after his first practice with the Cowboys on Monday. And I know from experience thats really important. You dont need a million people telling you how to throw a slant route. You just need to go with what you know, be as comfortable as you can, and Im here to help.Sanchez signed with Dallas on Sunday, a day after he was released in Denver when he lost a battle for the starting job to second-year player Trevor Siemian. He could end up as the No. 3 quarterback when Tony Romo returns from a broken bone in his back.Its still not known when Romo will be ready. The Cowboys have yet to put him on injured reserve, which would force him to miss the first seven games before he could be eligible for a return. Coach Jason Garrett said the team was taking at least a couple of more days to decide.If Romo stays on the active roster, that probably means the Cowboys think he can be back by mid-October. Otherwise, he would have to wait until Nov. 6 if Dallas uses its option to return one player from IR on Romo.As for how it all relates to Sanchez, most of the possibilities are premature for a guy who has barely opened the playbook in Dallas.Hes worked very hard in the last 24-36 hours trying to get comfortable with what were doing, coach Jason Garrett said. Hell pick it up. Hes seen a lot of different offenses in his life. Hes got to learn quickly, and thats where his focus is.Sanchez, the fifth overall pick in 2009 by the New York Jets, played in AFC championship games his first two years in the NFL. He wasnt as good the next two years, though, and was cut after missing the 2013 season with a shoulder injury.Following two seasons in Philadelphia, the Broncos acquired Sanchez after Peyton Manning retired and Brock Osweiler went to Houston in free agency. That didnt work out, so now hes backing up a fourth-rounder in Prescott, who took over at No. 2 when Kellen Moore broke an ankle in training camp. and became the starter when Romo got hurt.Maybe things didnt go perfectly as planned, but Im here for a reason, said Sanchez, who has 72 starts and 37 wins in 75 career games. You owe it to the guys around you to keep working hard whether thats scout team or whatever it means. If I get to see the field, great. If not, great.The Cowboys made room for Sanchez by waiving second-year player Jameill Showers, who spent most of last season on the practice squad and signed to return there again on Monday.Even with Showers return, Sanchez will have by far the most experience among the healthy quarterbacks.Hes started a lot of games, Garrett said. He was a very successful college quarterback. We played against him in our division, so weve seen him up close. Hes an experienced guy who has a lot of ability. We thought it was a good opportunity to add to the depth of our quarterback position.And with a guy who can relate to the rookie getting ready for his first start.Game notes DE Charles Tapper said doctors discovered a broken bone when he had trouble with his back in training camp. Hes been out since early in camp. The fourth-round pick said he expects to miss the opener but could be ready by the second or third game. ...
