In the past, facing the 49ers defense has been a running backs worst nightmare. So far this year, however, opposing backs have been feasting on the Niners, which would bode well for Rams running back Daryl Richardson, if he wasn't dealing with a foot injury.
The 49ers have allowed a league-high 73 Fantasy points to running backs through three games, including at least 10 in each game. They haven't necessarily given up huge yardage totals (just 112.7 per game), however six touchdowns have been put up on the board against the 49ers by running backs.
Richardson is officially probable for Thursday's game after getting through practice Wednesday. However this is the same foot injury that forced him to miss all but one snap in Week 3, so Fantasy owners are rightly a bit wary of leaning on Richardson again.
Opinions on Richardson's Fantasy value vary widely; of our three Fantasy experts, one has him ranked 23rd for backs this week and one has him 37th, while Nathan Zegura doesn't have him among his top 48. Richardson has plenty of boom-or-bust potential in Week 4, and should be considered a risky start.
