Here are some highlights from our San Francisco 49ers' chat, which was held earlier Thursday:Jeff from Syracuse: Do you think the 49ers should target a WR in free agency like Emmanuel Sanders given their lack of success in targeting WR's in the draft?Bill Williamson: ESPN Insider Adam Caplan suggested it last week. I don't think it will happen unless Boldin leaves. Keeping their own free agents will be the focal point of that offseason.Josh from Riverside: Are the replacements for Fangio and Roman currently on the team?
