Is there hope for Ridley?

Most expected Stevan Ridley to remain one of the more reliable fantasy stud running backs this season after racking up 1,263 yards and a dozen scores on the ground last year. It hasn't turned out that way, though, as he sports an embarrassing 3.7 yards-per-carry average for a total of just 174 yards and zero scores through four games. He missed last week's game due to a knee/thigh injury, but it appears that he will be back in the mix for Week 6's game versus the New Orleans Saints. What can we expect from him this week and beyond?
