is a win-win for both the quarterback and the organization. Dalton gets a chance to to return to his native state of Texas while joining a team with championship aspirations. The Cowboys get a proven backup quarterback who is more than capable of leading a team to victory if anything should happen to starter .While he is no longer a starter, Dalton is joining a Cowboys franchise that has enjoyed unique levels of succe s from their backup quarterbacks in the past. Several of those former backups helped contribute to championship-winning teams. A few of them carved out Hall of Fame careers.Let's take a look at some notable quarterbacks Dalton is joining as Cowboys backups, as we rank them 1-5. Getty Images 5. Bernie KosarJimmy Johnson, Buster Skrine Jersey who coached Kosar at the University of Miami nearly a decade earlier, and the Cowboys signed the former Pro Bowl quarterback after Bill Belichick and the Browns released him late in the 1993 season. In Week 11, Kosar came off the bench to lead the Cowboys to a five-point victory over the , a win that helped the Cowboys win the NFC East as well as earn the No. 1 seed heading into the playoffs.Kosar was again called into action after starting quarterback Troy Aikman suffered a head injury in the NFC Championship Game. Kosar, who led the Browns to three AFC title games during his time in Cleveland, helped the Cowboys punch their second consecutive ticket to the Super Bowl when he hit Alvin Harper for the game-clinching touchdown in Dallas' victory over San Francisco.Aikman, despite still feeling the effects from his head injury, started -- and played well -- against the in Super Bowl XXVIII. Kosar still got a chance, albeit briefly, to play in his first Super Bowl, taking a kneel down near the end of the Cowboys' 30-13 victory. The Super Bowl would be Kosar's last game with the Cowboys. The first overall pick in the 1985 draft, Kosar would spend three seasons at Dan Marino's backup in Miami before retiring after the NFL Chicago Bears Jersey 1996 season. Getty Images 4. Danny WhiteWhile he would back up Staubach for four seasons, White was the Cowboys' starting punter during his first nine seasons with the team. He rarely saw time on offense during those first four seasons, however, with just one start under his belt upon replacing a retired Staubach as the team's starting quarterback entering the 1980 season.White enjoyed immediate succe s as a starter. In 1980, White led the Cowboys to a 12-4 record and an appearance in the NFC Championship Game, a game they lost to their rival. In 1981, White led the Cowboys back to the NFC title game, where they lost to thein a game that is remembered by Joe Montana's game-winning touchdown pa s to Dwight Clark with under a minute left.In 1982, White earned his first Pro Bowl selection while leading the Cowboys to yet another NFC Championship Game appearance. Once again, Dallas fell to a superior opponent, as the Cowboys were unable to stop John Riggins and the' punishing rushing attack. The Cowboys lost their next two playoff games with White, who retired after the 1988 season.While his regular season numbers rival Staubach's, White's 5-5 playoff record (compared to Staubach's 11-6 postseason record) is the main reason why White's place in franchise history is somewhat forgotten. Getty Images 3. Craig MortonThe fifth overall pick in the 1965 draft, Morton sat behind Don Meredith during his first four seasons in Dallas. With Morton on the bench, Meredith led the Cowboys to consecutive NFL Championship Game appearances in 1966 and Tom Waddle Jersey '67. Both times, the Cowboys lost in dramatic fashion to the Packers, who would then go onto defeat the AFL champions in the first two Super Bowls.Meredith, despite being only 31 years old, retired after a three-interception performance in Dallas' lo s to Cleveland in the 1968 playoffs. The job as the Cowboys' starting quarterback then went to Morton, who led Dallas to an 18-5-1 record during his first two seasons as a starter. Morton's succe s helped the Cowboys win their first NFC title in 1970.Despite his succe s, Morton lost his starting job to Roger Staubach during the 1971 season. While Morton was certainly an efficient player, Staubach's ability as a runner, as well as his ability to test defenses deep, ultimately led to the Cowboys enjoying even more succe s with Staubach under center.After serving as Staubach's backup through the 1974 season, Morton enjoyed a late career resurgence with the Broncos, helping Denver win their first AFC title in 1977. In six seasons in Denver, Morton compelled a 41-23 regular season record that included three consecutive trips to the playoffs.Shortly after his retirement following the 1982 season, the Broncos selected their next franchise quarterback, John Elway, who won two Super Bowls and five AFC titles before retiring after the 1998 season. USA Today Sports 2. Tony RomoA former undrafted rookie, Romo toiled for two seasons on the Cowboys' bench before finally getting his opportunity to play midway through the 2006 season. Romo, who replaced an ineffective Drew Bledsoe, immediately gave the Cowboys a spark while leading them to their first playoff berth in three years.Over the next decade, Romo would lead the Cowboys to three more playoff appearances. In the proce s, Romo earned four Pro Kyle Fuller Jersey Bowl selections while becoming one of the league's most popular players. Romo also rewrote the Cowboys' record book, as he is currently the franchise's all-time leader in career pa sing yards (34,183) and touchdown pa ses (248). Romo's succe s in Dallas may one day earn him enshrinement in the Pro Football Hall of Fame, as Romo will be eligible for induction in 2022.Like White, however, Romo's legacy includes playoff disappointment, as Romo won just two of his six career playoff spots. His two biggest playoff lo ses include a 12-17 lo s to thein the second round of the 2007 playoffs andcontroversial non-catch in Dallas' second round lo s to thein 2014. Getty Images 1. Roger StaubachIn 1969, Staubach was a 27-year-old rookie who arrived in Dallas after completing his military service. While the former Heisman Trophy winner's talent wasn't lost on Cowboys head coach Tom Landry, Landry and the Cowboys were, at that time, committed to Craig Morton, who that season replaced Don Meredith as the team's starting quarterback.While the Cowboys had succe s with Morton, the franchise, as they did with Meredith, continued to endure disappointing playoff lo ses. After falling to thein the 1969 playoffs, Morton and the Cowboys fell to thein Super Bowl V. Morton endured a rough outing against Baltimore's defense, throwing three interceptions that included a Mike Curtis' interception that set up the Colts' game-winning field goal with five seconds left.By 1971, Staubach had grown tired of his role as Morton's backup. Landry, aware of Staubach's frustration and -- more importantly -- Kyle Long Jersey of Staubach's immense talent, started inserting Staubach into the lineup. But, to the frustration of both Staubach and Morton, Landry didn't commit to either quarterback as his starter, oftentimes changing quarterbacksbetween playsduring the first half of the '71 season.Finally, after an embarra sing lo s in Chicago in Week 7, Landry decided to move forward with Staubach as his quarterback. The Cowboys' response to the news was jarring, as Dallas did not lose a game in which Staubach started during the '71 season. The move to name Staubach his starter paid off handsomely, as the Cowboys capped off the '71 season with their first Super Bowl victory,over the.Staubach remained the Cowboys' starting quarterback for the remainder of the decade, leading the Cowboys to three more NFC titles and another Super Bowl victory at the end of the 1977 season. Dallas' win in Super Bowl XII came against Morton, who enjoyed a career resurgence with the.
