The NFL world knows Jon Gruden is an old-school football guy, but Jared Cook’s explanation of film sessions suggests we’re underestimating the Oakland Raiders coach.

According to Michael Gehlken of the Las Vegas Review-Journal, Cook said Gruden is reaching deep into the archives for film.

The idea itself isn’t a problem, because Raiders players can see exactly how the technical part of the game has evolved. Plus, Cook’s explanation is hilarious.

But chalk up another victory for the crowd ready and willing to make jokes about Gruden’s mentality.

Since taking the Oakland job, he’s reportedly clashed with former punter Marquette King while making several odd personnel moves. Most recently, Gruden took a verbal swipe at top player Khalil Mack and criticized the 2017 defense.

It’s been an interesting offseason in Oakland. We’re looking forward to seeing how much of 1976 Gruden brings to 2018.
