A derogative term in fantasy football that describes a situation in which an NFL team uses more than one running back in a prominent role. For example, a RBBC happened in Miami, where Ronnie Brown and Ricky Williams were rotated throughout the game. RBBC sometimes makes it difficult for owners to depend on a back for a consistent level of performance. RBBCs have become more popular in recent years and have made featured backs such as Adrian Peterson and Chris Johnson even more valuable in drafts.
