At that time, the receivers were known as either ends or flankers, with the end lining up wide at the line of scrimmage and the flanker positioned slightly behind the line usually on the opposite side of the field.

As the transition from starters going "both ways" to dedicated offensive and defensive squads took place, players who did not fit the mold of the traditional positions began to fill niches. Those who were good pass catchers and blockers but mediocre on defense were no longer liabilities; instead, a position evolved to capitalize on their strengths. Many were too big to be receivers yet too small for offensive linemen. Innovative coaches such asPaul Brown of the Cleveland Browns saw the potential of having a larger receiver lined up inside, developing blocking techniques and passing schemes that used the unique attributes of the tight end position.

Greater use of the tight end as a receiver started in the 1960s with the emergence of stars Mike Ditka and John Mackey. Until then most teams relied on the tight end's blocking as almost a sixth offensive lineman, rarely using them as receivers.[1] In addition to superb blocking, Ditka offered great hands receiving and rugged running after a completion. Over a 12-year career, he caught 427 passes for over 5,800 yards and 43 touchdowns.[1] Mackey brought speed, with six of his nine touchdown catches in one season being breakaways over 50 yards.[2]
