At the other extreme are "power backs": bigger, stronger players who can break through tackles using brute strength and raw power. They are usually (but not always) slower runners compared to other backs, and typically run straight ahead (or "North-and-South" in football terminology) rather than dodging to the outside edges of the playing field (i.e. running "East-and-West") like shorter, quicker, lighter backs will often do. Power backs from previous generations such as Jim Brown and Larry Csonka were often classified as fullbacks, but halfbacks such as Jerome Bettis and Steven Jackson also exemplify the power back position. More recent examples include Marshawn Lynch, LeGarrette Blount, Frank Gore of the New York Jets, Leonard Fournette of the Tampa Bay Buccaneers and Derrick Henry of the Tennessee Titans. For many years the “power” running back was the central component of an offense. In that time period formations and rhythm favored this type of player. This sort of offensive scheme is now a rarity, as “power backs” take on supporting roles behind faster and more versatile running backs.
