The Cardinals used Alfonso Smith as their primary back in the absence of Beanie Wells in Week 3, and Smith responded with 54 yards on 17 carries.
Smith also had 21 yards on three catches. It looks like he’s the preferred in-house option over Chester Taylor, but we wouldn’t go rushing to the waiver wire to pick Smith up. Smith lacks instincts between the tackles and is more of a straight-line runner, struggling to make defenders miss. He’s going to go back to the bench when Wells (hamstring) returns, which should be soon.
