RB

RB is an acronym for running back, which is an offensive position in football. The running back is primarily used to run the football in order to gain yards but is also responsible for blocking and catching the ball.

RBs typically line up next to or behind the QB. It is the second most important offensive position in the NFL and is used to keep defenses off-balance along with the passing game. RB often appears as RB1 or RB2 in fantasy football leagues to indicate the starting and second starting running backs on a team. Some examples of famous RBs include Jim Brown, Emmit Smith, Walter Payton, Adrian Peterson, Eric Dickerson, Gale Sayers, LaDainian Tomlinson, and Barry Sanders.
