Art Shell (Oakland Raiders)
Al Davis is a man who demands loyalty from his players and his coaches. John Madden and Tom Flores were both lifelong Oakland Raiders. So naturally, Davis would stick to that approach when he appointed Art Shell head coach in 1989. To be fair the former Hall of Fame tackle endured some problems early that didn’t help including the infamous Todd Marinovich experiment that blew up spectacularly in their faces.
Still, Shell had plenty to work with during his time in Los Angeles. He had Hall of Fame veterans like Marcus Allen and Howie Long making up the core of the team. Then there was eventual Hall of Fame wide receiver Tim Brown, Pro Bowl pass rusher Gregg Townsend, Pro Bowl corner Terry McDaniel and even Hall of Fame safety Ronnie Lott for a couple of years.
Those teams were good enough to reach the Super Bowl. Yet they were never able to get past the Buffalo Bills. Though many would say his 10-6 loss to Kansas City in 1991 was the worst of the bunch.
