I think it has more to do with the fact that Lewis has proven to be a consistent winner. The bengals have competed for a playoff spot almost every year he's been there. The bengals from the 90's and early 2000's were basically the browns of now.
Lewis made the playoffs once in his first 8 years, and lost by two TDs.
How did he last that long?
It was after all that time that he started making the playoffs as a wild card team, losing every time. So even AFTER the run of playoff appearances, Lewis STILL did not have a single playoff victory in 15 seasons. At this point, they had a near-impossible collapse in a loss to Pittsburgh. That alone would doom a coach.
At that point, they fell off and missed the playoffs two more years.
17 years. Zero playoff wins.
It was at THIS point, Bengals’ management decided it was time for an extension.
Don’t tell me they are better than before Lewis came. They have had more players in legal trouble than any team in the league and no playoff wins during this coach’s tenure. It is mind boggling that Marvin Lewis has a job.
