What roles for Moss, Jacobs, Ginn?

SANTA CLARA -- Brandon Jacobs and Ted Ginn have not played in the 49ers' first two games of the season. And Randy Moss has played fewer than one-third of the team's offensive snaps.

That could change in future weeks, and coach Jim Harbaugh likes the mystery to build.
"There are a lot of possibilities there, and you like to have your opponent think about all those possibilities," Harbaugh said Monday, one day after the 49ers' 27-19 victory over the Detroit Lions.In training camp, it appeared as if Jacobs would be the 49ers' short-yardage back, Ginn would handle the return, Moss would be the No. 2 wide receiver behind Michael Crabtree.But after two games, Jacobs (left knee) and Ginn (right ankle) have been inactive due to injuries. And Mario Manningham, not Moss, appears entrenched as the starter opposite Crabtree.That's quite a departure for Moss, who ranks among the all-time NFL receiving leaders. Among the 49ers' receivers, Moss ranked fourth in playing time behind Crabtree, Manningham and Kyle Williams on Sunday nightRELATED: 49ers play time -- Moss was No. 4 receiver
"Nobody around here ever gets caught in 'The Guy' terminology," Harbaugh said. "It's about us. It's about the team. There's no evidence he (Moss) is concerned about 'The Guy' tag. He knows football. He knows the team that plays the best is going to win the game. He's about that."Early indications are that Jacobs might not be ready for Sunday's game against the Minnesota Vikings. Ginn could be available to return to action, but it's not known whether he' will unseat Williams as a return man."We know what those guys can do," Harbaugh said of Jacobs and Ginn. "We know what their role is, and it is carved out. But at the same time, we're going to play the guys you feel each week that give us the best chance to win and are practicing better and whose ultimately is going to play better in the game. You also need to see that on the practice field."
