49ers WR Kyle Williams' offensive snaps took a significant dip in Thursday night's Week 4 win at St. Louis. Williams was playing about 75 percent of the downs coming into the game. He only played 32 percent against the Rams, as the 49ers tried to work Quinton Patton into the mix more. Unfortunately, Patton left the game with a foot injury after playing only seven downs. The Niners are clearly mixing and matching at No. 2 wideout. Jon Baldwin played 16 snaps in his season debut.
