Al Davis had grown sick of watching his rivals beat up on the Oakland Raiders, outplaying, outcoaching and even out-toughing his team. The swagger that once made the Raiders the NFL's most intimidating team and contributed so much to his mantras of "Commitment to Excellence" and "Just Win Baby" had long left the franchise. After suffering through three straight losing seasons for the first time since joining the franchise more than four decades ago, Davis reached back into the past to try to restore that aura. Davis introduced Art Shell as his new coach Saturday, bringing back his former Hall of Fame offensive lineman and head coach to turn his struggling organization around. "It may take us a short while, but we'll get that nastiness of the Raiders back," Davis said. "That's one of the reasons I'm going to depend on the great Art Shell to help us get that done."
