In football, FB stands for fullback. The fullback is an offensive position that blocks defenders and carries the ball.
The fullback can line up in several different areas on the field, but most often he lines up in the backfield to block for the halfback.
There is rarely a need for fullbacks in modern football. In most offensive formations, there is at most one fullback on the field.
To match up with larger defensive players, fullbacks must carry a lot of weight due to the amount of blocking they perform.
In Football, What is the Role of the FB?
FBs are known for their on-field duties, but do they really do anything else?
The main duties of fullbacks on the football field are run blocking, carrying the ball, and pass blocking.
Run Blocking
It is the FB’s primary responsibility to block runs. These players are responsible for running out in front of the running back and blocking players.
A fullback will usually block through lead blocking, which involves running through the hole created for the running back first.
After the running back gets through the hole, the fullback blocks the player attempting to make the tackle, allowing the running back to break free.
To play their position effectively, FBs must usually take on linebackers on these plays, so size is necessary.
Pass Protection
On some plays, the FB is going to be tasked with the duty of protecting the quarterback. The fullback will not be the first line of defense as that job is left up to the offensive line.
The fullback will stay in the pocket and simply wait to see if any defensive players are able to make their way through the line.
If a player is able to make his way through the offensive line the fullback must then block them before they reach the quarterback.
Since fullbacks are capable blockers they are usually able to lay an effective block in these situations.
Carry The Ball
It is not uncommon for the fullback to carry the ball in his hands whether or not he has it in his hand.
It is most likely that a short-yardage situation will lead to fullbacks getting the ball.
In a third-and-one situation, a team would only need one yard to gain the first down. A fullback is one of the largest ball carriers, making him effective in these situations.
In most NFL teams, fullbacks do not play as receiving weapons, but the San Francisco 49ers have made fullbacks a key part of their offense.
