Top 25 NFL running backs by Sportingnews

6. Willis McGahee, Baltimore Ravens. On an offense that can only run the ball, McGahee was the runner. He is a versatile rusher who can attack the edges as well as take on defenders between the tackles.

7. Frank Gore, San Francisco 49ers. Gore has carried his team in recent seasons and established himself as one of the league's premier backs with little help. With Mike Martz in the fold as the Niners' offensive coordinator, look for Gore to become a force once again as a dual threat runner and receiver.

12. Clinton Portis, Washington Redskins. Another back who is a tremendous fit for the zone-blocking scheme. Portis is a power runner with the vision and cutback ability to find daylight and get to and through linebackers.

14. Edgerrin James, Arizona Cardinals. Although James is on the downside of his career, he is still a productive runner who will benefit from the run-first mentality in Arizona.
