The NFC North side have secured just one win in 2013, having been beaten 44-31 by the Green Bay Packers last night.
The running back told reporters: "Really, the offence didn't see the field much [yesterday]. I felt like Christian [Ponder] did a good job. It's black and white, we understand what it is.
"Last week the offence didn't play great. We didn't play that great [last night]. Our defense struggled a little bit. We have just got to put it all together.
"I feel like once we do that we can get this thing back on track. I think when you look back on it you're like man, if we could just put it together, we can get something going."
The Vikings are currently last in their division.
