Finding a running back for fantasy football is difficult because every NFL coach treats the position differently. Today we are seeing more and more running back-by-committee approaches where coaches will use more than one running back extensively.
In this article, the running back situation for every NFL team is analyzed and broken down into three categories. The three categories are bell cow, feature and committee. Bell cow describes a situation where there is one true running back and there's not a lot of depth behind the starter. Feature describes when there is a definite starting running back, but there is a talented rusher behind him who will contribute. This rusher's contribution won't take too much away from the starter's statistics, though.
Finally, the committee describes a team that will use two or more backs throughout the season and will use both of them often. Committee's are often a fantasy football owner's nightmare since it's difficult to determine which rusher will have the bigger game on a given week.
