Previous head coaching experience was an important factor for John Elway, who’s now at the controls for the Broncos. Fox had an nine-year run in Carolina (not eight as I initially wrote), where he won one NFC title and posted a 78-72 regular season record.
Koetter worked as head coach at Boise State and Arizona State. Dennison has not been a head coach but had strong ties to Denver as a former Broncos player and coach.
Houston would have hated to lose him, but it would have been a survivable blow as Gary Kubiak calls plays.
Jacksonville would have likely struggled to replace Koetter, as Jack Del Rio’s staff is moving forward with only one-year contracts.
Koetter had a good year with some severe limitations with the Jaguars. That Elway identified and interviewed him was big. I’m sure that doesn’t make Koetter feel better about losing out, but it should. I suspect he’s a head coach in the league before his final football bio is written.
