Fullback
In American football, a fullback (FB) is a position in the offensive backfield. Traditionally, the duties of a fullback are split between power running and blocking for both the quarterback and other running backs.
Many of the great runners of the history of American football have been fullbacks, notably Jim Brown and Larry Csonka, but in recent years the position has evolved to be more a blocker than a runner, with occasional pass-catching duties. The remaining prominent fullbacks in the NFL, such as Mike Alstott, are typically employed for breaking through tight defensive alignments, often in short-yardage situations, or for screen passes. As a result, fullbacks are typically less known for speed and agility than for muscularity and the ability to avoid being tackled by knocking down defenders.
[edit] Criticism of position
Some fans and experts take issue with the position because fullbacks are often wasted as an extra running back or additional blocker. Often, critics want the fullback more involved in the running game. Special plays designed for the fullback (or H-back formation) were popularized by Coach Joe Gibbs. There is growing criticism that at the college and pro levels, capable white tailbacks are forced to bulk up and become fullbacks, because the common conception is that white tailbacks do not possess the natural speed and elusiveness of black athletes needed to succeed as a running back in the higher levels of the game.
The fullback position has become somewhat of a cult phenomenon with the Madden video game series. Many gameplayers will call the play outloud before the snap while near the goal line and affectionately say they are going to "feature the fullback".
