I guess this isn't the day to worry about the San Francisco 49ers' depth at receiver.It was a huge question going into the season. However, if Week 1 is an indication of how the 49ers are going to go about the passing game with Michael Crabtree and Mario Manningham hurt, depth might not be an issue.New addition Anquan Boldin had 13 catches for 208 yards. Nearly every yard came in the clutch. Tight end Vernon Davis continued his 2012 postseason chemistry with quarterback Colin Kaepernick with six catches (and two touchdowns) for 98 yards.
