Player talent will always trump the impact of coaching in a league where every team essentially has the same options in the playbook, but a good coach can make his mark by figuring out which concepts are building blocks. Sean McVay engineered an instant turnaround in Los Angeles last season, signing upgrades around Jared Goff and Todd Gurley in free agency, then implementing an up-tempo offense heavy on play-action passes and crossing routes.
The Rams were a huge surprise, but there were other developments that played out as expected under new coaches last season. The 49ers continued Kyle Shanahan's tradition of piling up pass attempts and yards but not passing TDs, and the Jaguars leaned on Leonard Fournette to batter opponents between the tackles under the direction of Doug Marrone and Nathaniel Hackett.
The 2018 offseason featured a rare degree of upheaval, with 19 teams replacing either their head coach, offensive coordinator or both. Some of the changes essentially were cosmetic and hint at a desire for continuity, while others point toward major changes to come.
We'll focus our attention toward the more impactful hires, highlighting the seven teams that changed head coaches, as well as the five that ventured outside their organization to hire a new play caller. There were seven additional teams that either replaced their OC with an internal promotion or hired a coordinator who won't call plays.
