Reason II: Nobody knows the Rams roster better than he does
When any NFL coach has achieved a certain level of seniority with their team, they naturally become the go-to guy in terms of resolving challenges for players and less senior coaches. It's natural, an organic matter of asking someone who has been around long enough to know who to contact or how to solve a daily enigma.
It happens in all organizations, not just in the NFL or even professional sports organizations. Inevitably, there is someone who has been in the organization who helped to navigate through a new software upgrade, a new hire of a key executive, or simply has had successful experience at rolling out the welcome mat for new faces.
Along the way, relationships form. Those interpersonal relationships can prove to be invaluable when it comes to motivation and effective assessment of talent. Knowing what makes a player tick, their strengths and weakness, what motivates them and what makes them check out, can be the difference between winning and losing.
Since he has been with the Rams for the entirety of Sean McVay's tenure, Coach Shula has great insight over what the team, and the head coach, are looking for from players. Better still, he has the experience to know how to get players to that level too. Coach Shula has served under some great NFL defensive minds: Coach Wade Philips, Coach Brandon Staley, and Coach Raheem Morris. With each new season, and on each new assemblage of coaches, Shula has had the opportunity to learn, and grow, in his own coaching abilities.
