Cardinals Head Coach Ken Whisenhunt reiterated on Monday there is no immediate rush to sign a new running back, but whoever it is, he will likely be asked to complement Wells, the starter, and prove he is better than Smith, who has moved up the depth chart.
So what type of back are the Cardinals eyeing?
"One that can do a little bit of everything," Whisenhunt said. "Obviously, someone that can help on third down, but be a good first- or second-down back. But it's not something we're just going to do overnight.
"We're going to do some research and try and get the right fit. There may be a player on another team right now that will become available at some point."
