The Dallas Cowboys are preparing for the ninth coach in franchise history. What started with the legendary Tom Landry will move on now that the team has parted ways with Jason Garrett. The men who have run the show on the Dallas sideline.
Tom Landry

Tom Landry was remarkable in his reign as Cowboys coach. So often coaches of expansion teams never see success. Landry coached for 29 years from 1960-88. He was 250-162-6 and 20-16 in the postseason. Forty-six of those losses came in Dallas’ first five seasons, which tells you how incredible Landry was once the franchise was entrenched in the NFL.
Jimmy Johnson

After Jerry Jones unceremoniously dismissed Landry, he brought on college teammate Jimmy Johnson, who was a great success on the college level. Johnson continued it in the NFL. He was 44-36 in five seasons as Cowboys coach from 1989-1993. Dallas won two Super Bowls under Johnson. In his final three seasons, the Cowboys went 36-12.
Barry Switzer

After Jerry Jones could no longer co-exist with Jimmy Johnson, he turned to another friend/coaching colleague, Barry Switzer. The former Oklahoma legend won one Super Bowl and was 40-24 in four seasons.
Chan Gailey

Chan Gailey coached for two seasons and went 18-14. There were two playoff berths and one NFC East crown before he was out.
Dave Campo

Dave Campo’s three-year run was unsuccessful. He was 15-33 and did not get the team to a postseason game.
Bill Parcells

Bill Parcells brought a Super Bowl pedigree to Dallas off his success with the NFC East rival New York Giants earlier in his coaching career. Parcells made it through four seasons with two playoff berths. He was 0-2 in the postseason. Overall, Parcells finished with 34-30 in the regular season.
Wade Phillips

Wade Phillips had a nearly four-year run with the Cowboys as head coach. He was 34-22 in the regular season before being let go mid-way through the 2010 campaign. Phillips won two NFC East championships but was 1-2 in the postseason.
Jason Garrett

Jason Garrett took over for Wade Phillips during the 2010 season. Overall, he went 77-59. There were three NFC East championships and a 2-3 mark in the postseason. There were three double-digit win seasons and four others where Dallas finished 8-8.
And …

There will be big names floated with arguably the biggest head-coaching gig in the NFL. One thing is certain, however, whomever takes the position will have to coach the players on the field and also make sure he can co-exist with Jerry and Stephen Jones and the power they display in ruling America’s Team.
