Here are some highlights from our San Francisco 49ers' chat, which was he'd earlier Thursday:Tristan Arostegui from San Francisco: Would getting a healthy Crabtree back turn the offense back into last year's form or would there still be a missing piece?Bill Williamson: Eventually, but it may take some time. Even if he is back by Mid-November, it may take a few weeks for him to knock off the rust. But if the 49ers go into the playoffs with Crabtree 100 percent, that will be a huge advantage.
