CSN Bay Area expects Kyle Williams to open the season as the 49ers' No. 2 wide receiver. If so, he'd do it over Marlon Moore, who started all four preseason games, and rookie Quinton Patton, who figures to be the No. 3 receiver. "He's had an extremely good camp," coach Jim Harbaugh said of Williams. "(He's) getting better, getting faster. I think he's come back stronger and faster than he was before." Jon Baldwin and Chris Harper will likely be scratched on game day.
