Fullbacks

Fullback is a term used in two codes of football: association football (soccer) and American football. In soccer, a fullback is a defender who plays on the left or right flank. They typically form part of the back line, defending against wingers and clearing wide areas, while also contributing to build-up play. In many modern systems, fullbacks provide attacking width through overlapping runs, crosses, and progressive passes, and the balance between defense and attack varies by formation.

In American football, the fullback is a backfield position traditionally used as a lead blocker for the running back and as a pass protector. Offenses historically relied on a powerful blocking fullback for running plays; in recent decades the role has diminished in many schemes, as offenses favor multiple-tight-end sets or two-back alignments. Some teams still use a fullback for short-yardage rushing or as a versatile H-back who lines up in multiple spots.

Tactics and development: In soccer, fullbacks balance defensive duties with attacking support. They defend wide channels, track runners, and prevent crosses, while providing width in build-up through overlapping runs, crosses, or progressive passes. Their responsibilities vary with formation: four-defender systems emphasize steadiness, while wing-back setups assign greater forward responsibility to the same players. In American football, the fullback's role depends on the scheme, often emphasizing blocking, pass protection, and occasional short-yardage rushing or receiving.

Notable players: In soccer, well-known fullbacks include Cafu, Roberto Carlos, Dani Alves, and Philipp Lahm. In American football, notable fullbacks include Mike Alstott and Kyle Juszczyk.
