‘The presence of longtime offensive line coach Bobb McKittrick is felt around the 49ers’ practice facility every day. He coached in San Francisco for 21 years before he died in spring 2000 of bile duct cancer. The team kept his locker intact under a glass encasing inside the coaches’ locker room. Every year, the top offensive lineman earns an award named in his honor. The 49ers even have two running plays named after him.’
