ARLINGTON, Texas -- Standing at a podium on the main concourse with the largest video board in sports as a backdrop, Jason Garrett was announced as the eighth coach to lead the Dallas Cowboys on Thursday.

Garrett earned the job after going 5-3 during the second-half of the 2010 season in place of Wade Phillips, who was fired on Nov. 8.

Cowboys owner and general manager Jerry Jones listed wanting a culture change around Valley Ranch as one of his reasons for making the move from Phillips to Garrett, and those eight games confirmed to him he made the right decision.

"He's truly one of our own," Jones said of Garrett, who was a backup quarterback for seven seasons with the Cowboys. "We know him well for the qualifications that he has for this position, and I know that he has spent his entire life preparing for this day. He's well qualified."

Jones has so much respect for Garrett that he stressed the new coach will make the final call on who is on the coaching staff and indicated there will not be a player on the 53-man roster he doesn't approve of.

"Jason will have the final say on any person that leaves the coaching staff or comes to the coaching staff," Jones said. "There won't be a player on this team that Jason does not want on the team."
