And when the Bengals hired former Cleveland Browns head coach - and Cincinnati Bengals offensive coordinator - Hue Jackson as an assistant, it seemed like Lewis's time as head coach would be coming to a close. That's a significant decline from the previous two seasons under Gary Kubiak, when the Broncos went 21-11 in the regular season and won a Super Bowl.
Lewis told his coaching staff on Monday he was leaving in what has been deemed a new direction for Bengals owner Mike Brown.
The Denver Broncos fired head coach Vance Joseph while the Miami Dolphins fired Adam Gase.
The Bengals coach was sacked after 16 seasons with the organization, ending his stint as the second-longest tenured head coach in the league.
Given how many black head coaches lost their jobs in 2018, it is important for successful black head coaches like Lewis to get those additional opportunities to show that one or two worse-than-expected seasons aren't a reflection of their overall value to an National Football League team.

In his 16 years, Lewis compiled a record of 131-122-3 and was named Coach of the Year in 2009 when the Bengals won the AFC North with a 10-6 record. Well, Cincinnati was a woeful franchise who had missed the playoffs 12 years in a row when Lewis arrived.
Gase got off to a promising start when the Dolphins went 10-6 and clinched a playoff berth in his first season, though things soured after last year's 6-10 mark and only got worse this season.
Arizona apparently has seen enough and opted to part ways with Wilks, who becomes the first one-and-done coach since the 49ers fired Chip Kelly in 2016.
Per Cincinnati.com, Jackson is expected to interview for the Bengals head coach position.
