A fullback (FB) is a position in the offensive backfield in gridiron football, and is one of the two running back positions along with the halfback.
The receiving team lines up with one or two players downfield to catch the ball. The center makes a long snap to the kicker who then drops the ball and kicks it before it hits the ground. The player who catches the ball is then entitled to attempt to advance the ball.
Striker ST – Striker. A similar function as the center and wing forward. IF – Inside forward. In the old days an offensive line could consist of five attackers and include two inside forwards positioned between the wing forwards and the center forward and normally a little behind the other three.
Special teams are unique in that they can serve as offensive or defensive units and that they are only seen sporadically throughout a game. Special teams include a kickoff team, a kick return team, a punting team, a punt blocking/return team, a field goal team, and a field goal block team.
