A tight end is a position in American football that combines the roles of a receiver and a blocker. They line up next to the offensive line and can catch passes or help protect the quarterback. Tight ends are typically larger and stronger than wide receivers, allowing them to effectively block defenders. In addition to their blocking duties, tight ends are often targeted in passing plays. They can run routes and create mismatches against defenders due to their size and agility. Successful tight ends contribute significantly to a team's offense by providing both blocking support and reliable receiving options.
