Here are the highlights from our San Francisco 49ers chat, which was held earlier Thursday:T. Cam from Louisiana: Hey Bill! With all of the new additions the 49ers have on Offense, do you see this being a potential top 5 offense?Bill Williamson: We all saw how good Kaepernick when Crabtree came back last season. How good can he be with all of these weapons on the field together? I think it will help Kaepernick's in both passing and running game.
