No, the 49ers havent lost quarterback Jimmy Garoppolo for any snaps due to injury this year, but several other components of their offense have certainly gone down at one point or another.

Left tackle Joe Staley has missed nine games. His counterpart on the right side, Mike McGlinchey, missed the same four games as fullback Kyle Juszczyk, another key blocking cog. Star tight end George Kittle sat two games in the middle of the season, while center Weston Richburg was lost for the season earlier this month.

Yet the 49ers are 12-3 entering this Week 17 showdown at Seattle. Theyve won by running the ball, and theyve won by passing the ball. Theyre averaging 30.2 points per game, second in the NFL to only the Baltimore Ravens.
