Week 15 Start Em, Sit Em: Shonn Greene and Other Must-Starts at RB

In Week 15, the following five running backs are must-start fantasy options:

Shonn Greene, Jets

After a disappointing start to the season, Greene has come on over the past two weeks with four scores and over 200 yards rushing. He's also been a factor in the Jets' passing games, totaling almost 40 yards a game during the two-game stretch. The Eagles have allowed 269 yards and two scores to opposing running backs over the last two weeks, so Greene should be a safe start on Sunday.

Cedric Benson, Bengals

After rushing for 91 yards against one the NFL's best run defenses (Texans), Benson gets a shot at a Rams' defense that has allowed the most rushing yards of any team this season. This should be a game where Benson cracks 100 yards for just the second time in nine weeks.

Felix Jones, Cowboys

Injuries and a lack of production contributed to Jones losing his starting spot to DeMarco Murray, but he's getting another shot at the lead role with Murray out for the season. And after 106 yards filling in for Murray last week, Jones now faces fantasy football's worst run defense in the Tampa Bay Buccaneers.

Ryan Grant, Packers

Grant has been a non-factor for most of 2011, but he broke out in a big way Sunday against the Raiders. Two scores, including a 47-yarder on the Packers' first play from scrimmage, fueled a performance in which Grant rushed for 85 yards. With James Starks still hurting and a good matchup against the Chiefs upcoming, Grant should build on his Week 14 stat line.  

Roy Helu, Redskins

Finally, we can have some confidence in what Mike Shanahan will do with his running back. Helu has carried the ball 73 times (average of over 24 per game) over the last three weeks and he's responded with over 100 yards in each. The Giants can be run on, too.
