Next receiver up: Kyle Williams

Today 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. Tight end Vernon Davis continued his 2012 postseason chemistry with quarterback Colin Kaepernick with six catches for 98 yards and two TDs.

Kaepernick used all but 106 of his career-high 412 passing yards on his two primary options.

However, it won’t always be easy to get the ball to Boldin and Davis. The 49ers go to Seattle to face one of the game’s premier secondarys Sunday. Surely, the Seahawks will be focusing on shutting down those two players and forcing others to contribute.

The next option, if the Green Bay game was any indication, is going to be Kyle Williams. He was listed as the No. 2 receiver going into the season and that was the case Sunday. The Sacramento Bee reported Williams was on the field for 71 percent of the snaps. Other rotational receivers, Marlon Moore (21 percent) and Quinton Patton (five percent) were afterthoughts. Williams had three catches for 36 yards Sunday.

This is a week-to-week scenario, but it seems like after Boldin and Davis, Williams is the next option.
