Hanging inside each 49ers locker this week was a blue, gas-station work shirt with a personalized name patch. It's a familiar look for a Jim Harbaugh-coached team. "He wants us to be a blue-collar team and work hard every day," said rookie tight end Konrad Reuland, an undrafted Stanford product on the practice squad. Harbaugh unveiled the shirt's at the end of Saturday's team meetings, once the roster was pared to the 53-man limit. He wore his blue garb underneath a black sweatshirt at Thursday's practice, and special-teams coordinator Brad Seeley donned his own Friday. "I love 'em. They seem to love it to, as you see the guys wearing it," Harbaugh said. "It's not real complicated what it stands for -- a motivational symbol, if you will."
