Crennel, 65, went 2-14 with the Chiefs this season, his first full season as the team’s coach after becoming the interim coach following Todd Haley’s dismissal last year.
The Chiefs have gone 23-41 (an average of fewer than six wins per season) since Pioli arrived prior to the 2009 season.
Bills fire Chan Gailey as head coach
Chan Gailey’s three-season stint leading the Bills ended without him ever winning more than six games in one year.
The Bills fired Gailey Monday with a one-sentence statement, a day after he beat the Jets in the season finale. He finished 6-10 for the second straight year, and went 16-32 in three seasons with Buffalo.
More change could come in Buffalo, with the fate of GM Buddy Nix still uncertain. Roster turnover is also likely, with the fate of starting quarterback Ryan Fitzpatrick also shaky.
Jets fire Mike Tannenbaum, will keep Rex Ryan
There is change coming to the New York Jets, but it won’t involve head coach Rex Ryan. Team owner Woody Johnson dismissed general manager Mike Tannenbaum on Monday, while recommitting himself to Ryan after a 6-10 finish.
“I believe that he has the passion, the talent, and the drive to successfully lead our team,” Johnson said of Ryan.
Tannenbaum, who once worked as an assistant under Bill Belichick when the Patriots coach led the Cleveland Browns in the 1990s, was the architect of the Jets’ roster and had been with the team for 15 years. He had been GM since 2006.
Said Johnson of Tannenbaum: “Although he helped guide us to two consecutive AFC Championship games, we are not where we want to be, and a new general manager will be critical to getting this team back on the right track.”
Browns fire coach Pat Shurmur, GM Tom Heckert
New Browns owner Jimmy Haslam is undergoing a housecleaning.
The team dismissed coach Pat Shurmur and general manager Tom Heckert a day after completing a 5-11 campaign. Both men had deep ties to departed former team president Mike Holmgren, who left after Haslam took control of the team during the regular season.
Both Shurmur and Heckert were expected to be purged, as Haslam and new team CEO Joe Banner will likely hire their own team to oversee yet another reconstruction of the Browns, who have reached the playoffs just once since re-entering the NFL in 1999.
“This decision was not an easy one because of my relationship with Tom and Pat and the fact that they are both quality people,” Banner said. “Ultimately our objective is to put together an organization that will be the best at everything we do. On the field, our only goal is trying to win championships.
Shurmur went 9-23 in two seasons as the Browns’ coach.
Jaguars dismiss GM Gene Smith
The Jaguars fired general manager Gene Smith on Monday after four disappointing seasons, including the worst year in franchise history. Coach Mike Mularkey could be next.
Owner Shad Khan is waiting to decide Mularkey’s fate until he hires a new general manager, which could happen this week. Mularkey failed to make the Jaguars (2-14) better in his first season, setting a team record for losses and dropping eight games by 16 or more points.
Smith was the architect of the roster. He had been with the team since its inception in 1994, working his way up from regional scout to general manager. He became GM in 2009, compiling a 22-42 record while failing to acquire a single player who made the Pro Bowl.
‘‘Now it is time for the Jacksonville Jaguars to begin a new chapter,’’ Khan said in a statement. ‘‘We’re not looking back. I’ve made it clear from Day One that we pledge nothing less than to deliver the first Super Bowl championship to Jacksonville. Our fans have been remarkably loyal over the years, and they were truly outstanding this past season. We simply must do better for our fans.’’
Khan said the search for a new GM will begin immediately.
Arizona director of player personnel Jason Licht, San Francisco director of player personnel Tom Gamble and Atlanta director of player personnel David Caldwell have been mentioned as potential replacements.
Raiders fire assistant coaches
The Oakland Raiders fired offensive coordinator Greg Knapp and three other assistants a day after finishing their 10th straight season without a playoff berth.
Coach Dennis Allen announced Monday that special teams coordinator Steve Hoffman, offensive line coach Frank Pollack and linebackers coach Johnny Holland also have been fired.
Allen said it was a difficult decision and he appreciated the contributions the four coaches made this past season.
After finishing 8-8 the past two seasons, the Raiders went just 4-12 in Allen’s first season as head coach.
