1. Arian Foster, Houston Texans
Arian Foster has been the biggest surprise at running back this season, averaging 27.3 fantasy points per game. Owners were thrilled with his 200-yard rushing game to start the season and he has not shown any signs of slowing down.
With three games left, Foster remains the No.1 fantasy option.
2. Peyton Hillis, Cleveland Browns
Where on earth did Peyton Hillis come from this season? The bruising Browns running back has 11 touchdowns on the year and has been a must-start all season for fantasy owners.
Hillis is certainly making a case to be a top pick in next year's draft.
3. LeSean McCoy, Philadelphia Eagles
LeSean Mccoy has scored the third most points amongst running back this season and it is primarily due to his ability to catch the ball out of the backfield. McCoy leads all running back with 70 receptions and has been a must-start all season.
McCoy remains a top back for the final three games.
4. Adrian Peterson, Minnesota Vikings
The always productive Adrian Peterson has been at it again in the 2010 season. AP is having another big year at fifth overall in rushing and second in rushing touchdowns with 11 just behind Foster.
Peterson is averaging 20.8 fantasy points per game.
5. Darren McFadden, Oakland Raiders
Darren McFadden is the fifth best scoring running back in fantasy football even though he missed two games earlier this season. The third-year back has 993 yards on the season with seven touchdowns. McFadden has also been a solid receiver with 39 receptions.
McFadden is a must-start every week especially Week 15 at home against the Broncos.
6. Maurice Jones-Drew, Jacksonville Jaguars
Jones-Drew has been on a roll lately with six straight 100-yard games. Jones-Drew's only downfall has been his lack of touchdowns. MJD only has five touchdowns on the year but he has still be the sixth best scoring running back in fantasy football.
Which running back has been more of a surprise?
7. Chris Johnson, Tennessee Titans
Not quite 2,500 yards, but CJ2K has had himself a nice year. With over 1,100 yards and 10 touchdowns, Johnson has been a top fantasy back again this season. Johnson ranks seventh in scoring among running backs heading into Week 15.
8. Ahmad Bradshaw, New York Giants
New York's Ahmad Bradshaw has been a productive back all season long. No. 44 is seventh in the NFL in rushing and is eighth highest in scoring for running backs. Bradshaw does split carries with Brandon Jacobs, but Bradshaw's big play ability makes him the more valuable back.
9. Jamaal Charles, Kansas City Chiefs
Averaging 17.8 points a week, Jamaal Charles ranks ninth in running backs in fantasy points. Splitting carries with Thomas Jones has hurt Charles this season, but it is clear who the playmaker is in Kansas City. Charles has been more productive in recent weeks and should be big for fantasy owners in the playoffs.
10. Michael Turner, Atlanta Falcons
Michael Turner is fourth in the NFL in rushing and has 11 rushing touchdowns. Turner has been a reliable option for fantasy owners this season and is the 10th best scoring running back.
Turner will remain a top option for the final three weeks for fantasy playoffs.
