first person? you been in a cave? Linehan was a joke last couple years but he was considered very good in years like 2014.
Jason Garrett before he became head coach 2007-2012 was a coordinator
JASON GARRETT (2007-2012)

Jason Garrett was hired before Head Coach Wade Phillips was, a pick that Jerry Jones made as this selection was questioned at first. As Garrett began the season, he made Jones look like a genius. As an OC, he was credited for being making adjustments during the course of a game. After Phillips was fired in the middle of the 2010 season, he took over as interim coach and eventually given the full time job after the season was complete. Garrett continued to call the plays, never hiring an offensive coordinator until 2012 when he hired Bill Callahan. Garrett has relinquished the play calling duties for the 2013-14 season.
Bill Callahan’s fate has been written yet but our fans hope it is similar to the Landry days of the 70’s or the Turner-Zampese days from the 1990’s. We all want the end result to end up with a sixth trophy, much like his predecessors, he will have a lot of eyes watching his every call.
Unless of corse the cowboys success was all on Tony as some would like to claim.
