Kellen Winslow and Dave Casper fans might argue, but Mike Ditka and John Mackey just might be the the greatest tight ends ever to play in the NFL. Ditka played for the Bears, Eagles, and Cowboys, and he was a great blocker and pass receiver. He was a tough as nails player who thrived on competition. His rookie year with Chicago, Ditka had 56 receptions for 1,026 yards and 12 touchdowns. He was the 1961 Rookie of the Year. Ditka was the first tight end elected to the Hall of Fame. John Mackey played for the Baltimore Colts from 1963 to 1971 and the Chargers in 1972. He could do it all. A talented receiver, Mackey had the speed, and he averaged over 16 yards per catch. His main strength, however, might have been his devastating run blocking ability. Mackey had six touchdowns of 50 or more yards one year.
