4. Davis Webb
Current job: Denver Broncos quarterbacks coach
Webb just completed his second season as the Broncos' quarterbacks coach, with a key role in how well rookie signal caller Bo Nix performed. He is not far removed from his playing career, at 29 years old, which gives him familiarity with the direction of NFL offenses.
Campbell has been clear about Sean Payton's influence on him as a coach, and Webb has of course been on Payton's staff in Denver the last two years. So it's worth wondering if Payton will make (or already has made) a call encouraging Campbell to interview Webb for the Lions' offensive coordinator role.
Sometimes all someone needs is a chance. Webb may get a chance to interview as the search to replace Johnson gets going, and the trust Payton placed in him could be influential for Campbell.
3. Shane Waldron
Most recent job: Chicago Bears offensive coordinator

Waldron got a raw deal when former Bears head coach Matt Eberflus made him a scapegoat by firing him as offensive coordinator in the middle of this season. But it was also pretty clear his offensive philosophy didn't align well with the skill set of quarterback Caleb Williams, which when it comes down to it had to have pushed the Bears toward hiring Johnson as their new head coach.
Within the idea of Goff having a lot of involvement in the search for a new offensive coordinator, Waldron has history with the Lions' signal caller. Waldron was on the Los Angeles Rams' offensive staff from 2017-2020, going from tight ends coach (2017) to passing game coordinator (2018) to passing game coordinator and quarterbacks coach (2019) and back to passing game coordinator (2020).
Waldron seems easy to line up for an interview to replace Johnson in Detroit.
