You justified my analysis of being lazy in your response. Garrett was the OC of Dallas offenses from 2007-2010. The offense was successful enough that it led to all his head coaching interviews and offers. He was a good OC and play caller before stepping in as head coach, which seems to have been too much too soon for him.
“In January 2007, Garrett was hired by the Dallas Cowboys as offensive coordinator. He guided the Cowboys to the 2nd best offense in the NFL, which made him an attractive head coaching prospect. In January 2008, Garrett interviewed for the head coaching job of the
Baltimore Ravens and the
Atlanta Falcons, receiving offers from both, but ultimately opted to remain in Dallas.
[19] His salary for the 2008 season was nearly $3 million; the highest salary for an assistant coach in the NFL at the time.
[20] On December 29, 2008, the
Detroit Lions received permission to speak to Garrett regarding the team's head coaching vacancy according to ESPN sources.
[21] In January 2009, the
Denver Broncos also interviewed him as a possible replacement for fired coach
Mike Shanahan.
[22]He was also a finalist for the
St. Louis Rams head coaching position, to replace
Jim Haslett, the interim head coach.”
