Agree with the notion of a shake-up of the OL. Fix the OL and EVERYBODY (including the QB, WR's and the defense) will all look better immediately.
Here's an unstated alternative, which Singletary/Raye/Foerster might consider. . Start the forgotten man, Cody Wallace, at RG and de-activate Chilo Rachal for a time. Wragge is too valuable as a game day active 45 back-up at 3 positions (LG, C, RG), to move into the starting line-up. Sims and Pashos both have to be on the game day active 45, esp with Snyder being banged-up at RT. The numbers just won't work for the game day active 45, if Wragge starts. So, I wouldn't be surprised if Rachal and Wallace simply exchange roster roles for now. Such a move allows Rachal to catch a breather and restore confidence. Such a move also gets some ROI on the Wallace investment, and gets him valuable game experience for the day when he will eventually have to replace Heitmann at C. Every Niner center in recent memory (Heitmann, Newberry, Dahlman, Sapolu), all played extensively at OG before moving to C and taking over the line calls.
I also wouldn't be surprised if Jimmy Raye was allowed to bring in an Assistant OL coach, with whom he has collaborated in the past, to "assist" OL coach Chris Foerster, (much as Nolan brought-in Foerster to "assist" OL coach George Warhop, before Singletary actually replaced Warhop with Foerster). There are only a handful of OL coaches around the NFL, who are simply magic in developing offensive linemen and getting them to perform as a unit. I sure wouldn't mind seeing an OL coach with roots in the Giants, Miami, Denver, Pittsburgh Kansas City or Carolina systems.
