Jim Harbaugh insists he is staying at Michigan.

Responding to speculation he's returning to the NFL, the former San Francisco 49ers coach told ESPN he is not going anywhere.

"This is a choreographed message that comes up at this time every year before signing day," Harbaugh told ESPN. "It's people spreading messages to further their own personal agenda. But I'm on record right here, right now: I'm not going anywhere. I'm staying at Michigan. We have big plans here, and there's a lot we want to accomplish."

Former Ohio State star receiver and Fox Sports analyst Cris Carter has said Harbaugh is a potential candidate to lead the Green Bay Packers and Cleveland Browns.

After Harbaugh and the eighth-ranked Wolverines were celebrated Sunday at a banquet, he didn't want to discuss the topic much at a previously scheduled news conference to promote the team's appearance in the Peach Bowl.

Why did he address it with ESPN?

"To make a statement of it, to go on record and not be asked anymore after that by people who like to yap and ask questions," Harbaugh told reporters.

Campbell extended

Iowa State and coach Matt Campbell agreed to a contract extension through 2024, a sign that one of the hottest names in the annual coaching carousel is staying put.

The Cyclones have posted back-to-back eight-win seasons, and their six victories in the Big 12 this season were the most in school history. Iowa State's third-place finish in the league was its best in 40 years.

Snyder speaks

Bill Snyder made his first public comments since Kansas State announced Snyder would not return as coach next season following a disappointing 5-7 campaign that ended without a bowl game for the first time since 2009.

At a team banquet, Snyder used most of his nearly 30 minutes thanking his former players, support staff and family for all they did for him during his legendary 27-year career with the Wildcats. He closed with a special thank you to his family.

"You have been truly, truly special," Snyder told the crowd at the end of his speech. "There are no words that I could provide you right now that would adequately surmise my feelings, my passion and my love for each and every one of you."

Snyder won 215 games and two Big 12 titles at Kansas State and made 19 bowl trips.
