Williams will get the start at running back against Miami.
Arizona will be without running back Beanie Wells until Nov. 25 (at the earliest), after he was put on the injured reserve-designated to return list as of Sept. 26th. Wells has been battling turf toe and will need time to have it heal. The Cardinals brought back (via azcardinals.com) Alfonso Smith on a one-year deal to bolster the rushing attack.
Ryan Williams will be the starting running back while Wells is out. LaRod Stephens-Howling steps into the second spot on the depth chart while Smith is now third.
As bad as the Dolphins are against the pass, they are actually quite strong against the ground game. Miami boasts the third-best rushing defense, allowing a scant 65 yards a game. Regardless of which running back gets the call, this is going to be a tough matchup against the Dolphins' 4-3 defense.
Williams also has lost two fumbles in the first three games, so ball security is critical for the second-year back. Arizona doesn't do well rushing, gaining 82 yards per game on the ground.
Williams: 18 carries, 59 yards, 1 rushing TD
Stephens-Howling: 4 carries, 18 yards
