Jon Gruden and Al Davis last spoke on Feb. 18, 2002, which was the day Davis traded Gruden from the Raiders to the Buccaneers.

"God, I loved him, man," Gruden said of Al Davis. "It is different without him here. When he'd walk in, whether it was a defensive meeting, offensive meeting or special teams, you had to be ready. You don't want complacency to set in. That's one thing he never let happen. I'm going to make sure his spirit, his legacy, remain alive."

Davis passed away in 2011.
