Here are some highlights from our San Francisco 49ers' chat, held Thursday:Derek from Illinois: A big problem I notice when the 49ers play in Seattle is the lack of separation created by the receivers off the LOS. Do you think the 49ers will utilize more motion and stacked formations to help combat this?Bill Williamson: They haven't had this type of weaponry the last few times in Seattle. I expect the 49ers trying to come out throwing early to set a winning tone.
