With Adrian Peterson officially done for the season, Kerwynn Williams will once again have the Arizona Cardinals' rushing workload all to himself in Week 15. The last two weeks, as the team's primary running back, Williams has averaged 18.5 touches and 92.5 total yards per game. Besides getting a heavy workload in Week 15, Williams also has a favorable matchup, as the Cards face the Washington Redskins.

Washington has allowed 122.0 rushing yards per game with opposing backs scoring 19.8 standard fantasy points per game this season. In the last four weeks, their rush defense has gone downhill, allowing two 100-yard runners with three of their opponents gaining at least 160 rushing yards per game. Last week, the Los Angeles Chargers racked up 174 yards on 35 carries.
