SAN DIEGO -- The most important bit of film study for Bob Sanders didn't come when he was preparing to face the Chicago Bears in Super Bowl XLI, or the year he was named the NFL's defensive player of the year.
It was when his father brought home a video from the steel mill in Erie, Pa., footage of Marion Sanders swinging a 20-pound sledgehammer the way he did working those 17 1/2 -hour shifts for more than 30 years.
