Oakland Raiders head coach Jon Gruden is apparently mining old game film to prepare his team for the 2018 season.
Raiders tight end Jared Cook told reporters Monday that Gruden pulled out video from a game that appeared to take place in the 1970s, per the Las Vegas Review-Journal's Michael Gehlken:
