Starters: Joe Staley, Mike Iupati (pictured), Jonathan Goodwin, Anthony Davis, Chilo Rachal
One To Watch: Adam Snyder
This group has put the "offensive" in offensive line in the first three weeks of the preseason.
In addition to allowing way more sacks than they should, the line has allowed opposing defenses (who have been playing vanilla for the preseason) to put a lot of pressure on the quarterback.
Coach Harbaugh said the line was "violated" by the rush of the Houston Texans last week.
The line could see major changes based on who wins the starting center role. If newly signed Jonathan Goodwin can hold off Adam Snyder to win the role, it could free Snyder to take over for the struggling Anthony Davis or Chilo Rachal on the right side of the line.
These changes may only be superficial. Should the line struggle early, it will be a cause of major reflection given the number of high draft picks spent to acquire the current line (Joe Staley, Mike Iupati and Anthony Davis are all first-round picks).
Barring major changes in the next week and a half, this group will most likely be the major roadblock to an effective offensive effort in 2011.
