As a member of the 30-and-over club, 33-year-old quarterback Marc Bulger knew that he didn't have to practice on Monday. But he was on field, making sure he didn't miss anything. "As a quarterback, I think you realize that there's never an off day and you have to set an example," Bulger said. "This season, since I haven't really had an offseason, I think there's a lot I have to catch up on." ÃÂ The additions of Anquan Boldin, Donte' Stallworth and rookie David Reed might be interpreted as a wake-up call for the foursome of Demetrius Williams, Marcus Smith, Justin Harper and Eron Riley, but Derrick Mason said the young receivers are improving. "They're doing good," he said. "They're doing what the coaches have asked them to do. Go out there and play hard, make the play when it comes to you, and I think the good part about them is they have a good attitude about the situation that is in that receivers room. No one has any animosity. We're all out here trying to work, and those guys make us better because they're pushing each and every day. That's what you're supposed to have, guys below you pushing you to get better."
