Mike Johnson said he wouldn't "hide" Troy Smith -- meaning, presumably, that Frank Gore won't get 42 carries Sunday - but acknowledged the playbook will have to be pared back. "He's a going in there and doing everything he needs to do," left tackle Joe Staley said. "We're just trying to make it as simple as possible for him." "I'm still trying to figure out some of the things that he does well," Johnson said. "Watching him practice and now that I have a chance to see what he can do (I can) put a game plan together ... I get three days to kind of see what he does well."
