The usual scramble of firing and hiring N.F.L. coaches displayed perhaps a touch more impatience this year: Some coaches were dismissed even before the season ended.

But any expectations that all the turnover might yield a more diverse class of coaches were quickly dashed when the dust settled.

In all, seven coaches were fired, roughly in line with recent years.

What is perhaps more remarkable is who replaced them: All but one was white, and the hiring of one black head coach, Hue Jackson by the Cleveland Browns, was offset by the dismissal of Lovie Smith, who coached the Tampa Bay Buccaneers for just two seasons.

Two other black coaches, Jim Caldwell of the Detroit Lions and Marvin Lewis of the Cincinnati Bengals, fell under suspicion in news media reports that their jobs were in danger, but they have held on.
