Here are some highlights of our San Francisco 49ers' chat, which was held earlier Thursday:Ump from Italy: What do you think will be the toughest task in facing the Panthers Sunday in Carolina? Their front 4 seem very dominant; I am worried Kap may be getting his jersey covered in grass stains.Bill Williamson: Definitely front seven. Top notch unit, Kaepernick has to get the ball out quickly.RDC from Clovis, CA.: Hey Bill, the Niners have shown that they are built to play anywhere and everywhere.
