"For all the Detroit fans, what you don’t see is the work ethic that you’re getting. This guy is nuts. People thought I was nuts. This guy is freaking nuts, man."

Jon Gruden resigned as head coach of the Las Vegas Raiders—his last formal football coaching job—in Oct. 2021 after the release of a trove of emails that he sent from 2010 to '18 containing racist, misogynstic and anti-LGBTQ remarks.

Gruden visited Detroit Lions training camp Monday in Allen Park, where his good friend and protege John Morton is the team's new offensive coordinator. Gruden reiterated his desire to return to the sidelines as a coach.
