The Packers don't have an obvious future head coach on their staff

Just this week, former Green Bay Packers quarterbacks coach Ben McAdoo received his walking papers from the New York Giants. This marks the third time one of Mike McCarthy's assistants failed as a head coach.

Before McAdoo's demise, former Packers offensive coordinators Jeff Jagodzinski and Joe Philbin struck out on their own. Jagodzinski delivered two winning seasons at Boston College before drawing the ire of his boss. The school fired Jagodzinski one day after interviewing with the New York Jets, a professional mistake from which he never recovered.

Jagodzinski might not have faltered due to his coaching acumen, but Joe Philbin did. Philbin served as the Packers' offensive coordinator from during the early years of the Aaron Rodgers era, parlaying the team's fortunes into the top gig with the Miami Dolphins. While Philbin helped orchestrate in one of the greatest offenses in NFL history, he couldn't replicate that success in South Beach, never producing a winning record as a head coach.

While the track record of previous McCarthy assistants doesn't necessarily hurt the chances of others from receiving the same opportunity, it certainly doesn't help. Further complicating the matter, the Packers don't appear to have any obvious future head coaches on their staff.

Outside of former head coaches, teams typically target successful offensive and defensive coordinators to fill head-coaching vacancies. In theory, those assistants have the most experience of any non-headman and can transfer the skills and lessons learned from their previous organizations to their new ones. Those who have proven themselves particularly adept at calling plays move to the top of the list.

In Green Bay, McCarthy calls his own plays on offense, reducing the responsibility for his top offensive assistants. As for the other side of the ball, defensive coordinator Dom Capers has overseen a defensive regression in recent years. While Capers does possess some head-coaching experience from his time with the Carolina Panthers and Houston Texans, his age (67) further limits his appeal.

Edgar Bennett has served a number of roles in Green Bay, coaching running backs, wide receivers before his promotion to offensive coordinator in 2015. His wide-ranging experience could garner him some consideration in the coming years. However, the Packers' offensive struggles in Rodgers' absence doesn't reflect well on the coaching staff's ability to adjust to less-than-stellar talent, a problem plaguing most teams in search of a head coach. Bennett also hasn't called plays at any point in his coaching career. While not a death knell to his chances, the lack of play-calling experience makes him a less desirable candidate.

Someone further down the Packers' coaching ladder could emerge as a viable head coach in the future. Certainly, few knew about Sean McVay four years ago when he coached tight ends in Washington. Perhaps one of Green Bay's position coaches like Joe Whitt Jr. or Luke Getsy might become a viable candidate down the line.

But right now, the Packers' coaching staff doesn't appear to have the robust talent it once did.
