"Walk Around" Head Coach vs Offensive or Defensive Guru as Head Coach Walk Around HC (non-coordinator HC) There are some possible advantages to having a Head Coach that is the manager with both the Offensive and Defensive Coordinators being somewhat independent of the Head Coach. 1. HC focused on big picture. 2. Can maintain consistent team structure/process when Coordinators are fired. Note: Belichick is still the football guru even if other coaches hold OC and DC titles. Head Coach as Offensive or Defensive Coordinator The big disadvantage is that the most in-demand Offensive or Defensive Gurus get hired as Head Coaches. A Sean McVay type Offensive Guru had to be hired as the Head Coach, not as an Offensive Coordinator. Even if an Offensive Guru was available as an Offensive Coordinator, those types would not want to work for a Head Coach that was previously the team's Offensive Coordinator. It would be better for the Offensive Guru to work for a Defensive minded Head Coach. Similar to the limitations of hiring top Gurus as Coordinators instead of as Head Coaches, keeping top Coordinators is also more limited when Neither Coordinator can be promoted to Head Coach. Obviously long term, only 1 of 2 Coordinators can be promoted to Head Coach, but keeping 1 of 2 is better than keeping zero. Cowboys Specifically The Scenario where the Cowboys exit the playoffs without reaching the Super Bowl presents difficult questions in regards to Head Coach. Hiring a new Head Coach works better when a team tanks by mid-season and management knows they'll hire a new HC. GMs with a team in the playoffs or playoff contention to the end of the season generally won't contact potential replacements until their season is completely finished. What if Garrett Not Retained Kellen Moore: Not likely hired as HC by Cowboys in 2020 regardless of success in 2019. Kris Richard: He is not even the DC in 2019. Would they hire him as HC? Outside Hire: Unless the Cowboys tank by about game 12, they'll get a late start hiring a new HC. What if Garrett gets New Contract The contract would likely expire after 2022 (3 year deal). Both Moore/Richard can likely be retaining in 2020 (Richard as DC). Both Moore/Richard could be hired by other teams as HCs before 2022.
