Here are some highlights from our San Francisco 49ers chat, held earlier Thursday:Matteson from Washington, DC: How would you grade Aldon Smith since he has been back?Bill Williamson: Fair. Getting back into shape. He needs to getting going in it the next couple of weeksAdam from Sacramento: B-Dub... It seems to me that the blueprint against the 49ers has been to stack the box with 8-9 guys and play press coverage on their below avg WR since they can't get any separation.
