Randy Moss didn't attend the first two weeks of San Francisco's offseason program, but he arrived Monday in time for the first on-field coaching session. Matt Maiocco of Comcast SportsNet Bay Area reports that coach Jim Harbaugh suggested Moss spend the first two weeks at home. "It was eye opening," Moss said. "Today was the first day and we were moving so fast. Today felt like we'd been out here for a week or two." He will have to get up to speed fast. Barring injuries in front of him, Moss will have a difficult time just making the 49ers.
