(KPIX 5) — There have been several books written about former Raiders owner Al Davis, but there have been none like the latest. “Behind The Raiders Shield” is co-authored by two of Davis’ closest confidants, Jon Kingdon and Bruce Kebric.

It’s an eye-opening insight at Davis — how he treated people, how he drafted and how concerned he was about his own image. Dennis O’Donnell spoke with Kingdon on Gameday.
