[UPDATE] It looks like it's a done deal, according to an article from Todd Archer.
The Dallas Cowboys have reached an agreement with Jason Garrett on a five-year, $30 million deal to remain the team's head coach, according to league sources.
The Dallas Cowboys and Jason Garrett may come to terms on a deal very soon. ESPN's Chris Mortensen reports that the two parties are close to a five-year deal that will keep Garrett as the head coach of the Dallas Cowboys. Ed Werder adds that a source has told him that: "It's not done, but it's close."
Earlier today in his press conference Garrett was emphatic that he wanted to stay in Dallas and brushed off any questions about looking at other teams. Jerry Jones let Garrett work into the last year of his deal in 2014 after keeping him as coach through three consecutive 8-8 finishes. The gamble by Jones and the work of Garrett paid off in a 12-4 season for the Cowboys and a trip to the Divisional Round of the playoffs.
Once the deal is complete, the Cowboys will still have to work on retaining the rest of the staff. In Garrett's earlier press conference, he said that defensive coordinator Rod Marinelli had told him he would like to stay in Dallas.
