With the opening of training camp, the team seemed poised to take the next step; however, this soon changed. Within the first week of camp, the Cowboys released starting quarterbackQuincy Carter. The move came with no warning; reporters at training camp became aware something had occurred when Carter did not suit up for practice and was later seen being escorted from the Cowboys facility. Though never verified by Carter or the team, it has been speculated by the Cowboys, that his release was prompted by a failed drug test administered by the Cowboys, an action prohibited by NFL rules. Rumors began that Carter had already entered the second phase of the NFL's substance abuse program, meaning he had twice failed NFL-mandated random drug screenings. Test results are not made public but notices are sent to team officials. A third violation of the substance abuse program results in a mandatory suspension, and the Cowboys, unwilling to risk losing a starting quarterback during the season, began to monitor Carter with its own drug tests. Carter's formal protest of his release through the NFLPA as well as his subsequent troubles with drug addiction appear to lend credence to this scenario, According to the NFLPA. This move had a long-term effect on the team: Had Carter remained, second-year QB Tony Romo would have been fourth on the depth chart and likely cut from the team. When Carter left, Romo moved up to number 3, and was later a Pro Bowl starting quarterback for the Cowboys.
Regular season
would be the opening day starter for the Cowboys. His extensive experience and veteran presence was an asset to the team, especially to young undrafted practice squad addition Tony Romo, but failed to produce many points behind an inconsistent offensive line. Dallas' defense would also regress from the previous season, especially the secondary which lost starting cornerbackMario Edwards in free agency and longtime mainstay and team leadersafetyDarren Woodson due to injury. Following a loss to the Baltimore Ravens, Drew Henson would start the annual Thanksgiving Day game against the Chicago Bears. The game still provided excitement for Cowboys fans as a rookie running back Julius Jones, who had been injured early in the season and had just returned in the previous game, put on a masterful performance rushing for 150 yards and two touchdowns in leading the team to victory. Jones' momentum would carry over to the next game where he would rush for 198 yards and three scores in a dramatic win over the Seattle Seahawks. In only 7 starts Jones would rush for over 800 yards and seven touchdowns, though not justifying Parcells' decision to pass onrunning backsSteven Jackson and Kevin Jones in the draft. Bill Parcells would continue to mold the team steadily implementing his preferred 3-4 defense and allowing his assistant coaches on offense, particularly Maurice Carthon and Sean Payton, to take more control. Other notable additions to the team this year include linebackersRyan Fowler and Scott Shanle as well as former Heisman Trophy winner Eddie George in his final NFL season.
