A tight end is a position in American football that combines the roles of a receiver and a lineman. They line up next to the offensive line and can block for the quarterback or running backs, as well as run routes to catch passes. This versatility makes them valuable players on the field. Tight ends are often key targets in the passing game, especially in short-yardage situations. They can create mismatches against defenders due to their size and agility. Notable tight ends in NFL history include Tony Gonzalez and Rob Gronkowski, who have set records for receptions and touchdowns.
