Although Jon Gruden hasn't been a head coach in the NFL since 2008, he hasn't ruled out a return to the sidelines.

In an interview with Scott Reynolds of Pewter Report, the 53-year-old explained the interest he has received from around the league.

"I've met with several people—I won't deny that," Gruden said. "People—just about every year I talk about coming back to coach. I'm not in here every day at 4:30 or 4:00 in the morning watching pinball. You know? I'm preparing myself to come back. I am. Every day. I'm preparing to come back."

Gruden has been an analyst for Monday Night Football since 2009, also providing draft coverage with his "Gruden’s QB Camp" series where he talks with the top quarterback prospects in each class.

However, he believes his preparation could allow him to make a quick transition back to coaching.

"You can't come back unless you are totally wired with college football, personnel, schemes, the CBA, how people are practicing, trends, you know. You've got stay on top of this stuff," he explained.

ESPN's Adam Schefter reported in January that the Indianapolis Colts, Los Angeles Rams and San Francisco 49ers were all interested in hiring Gruden for the 2017 season, per Cork Gaines of Business Insider. However, the broadcaster rejected them all.

His salary is a good reason to stay in his current position. As of 2015, Gruden was reportedly the highest-paid personality at ESPN while making $6.5 million, according to the company's oral historian, James Miller.

Still, the coach won 95 games in 11 years with the Tampa Bay Buccaneers and Oakland Raiders. He also guided the Bucs to a Super Bowl XXXVII win. With his knowledge of the game, one shouldn't rule out a return.
