The Oakland Raiders have a lot of draft capital with new general manager Mike Mayock working his first NFL Draft later this month.

Jon Gruden has some pointed advice for the former draft analyst.

"Don't mess it up, dude," Gruden told Mayock. "I took a lot of slings to get you three first-round picks."

The Raiders acquired two extra first-round picks in trades of Khalil Mack and Amari Cooper.
