Duke Carlisle, the Texas quarterback the Kansas City Chiefs selected in the 1964 AFL draft, died Friday in Lockhart, Texas, after a seven-year fight with lung cancer. He was 84.

The Chiefs took Carlisle in the sixth round, 42nd overall, in the same draft in which the Green Bay Packers chose him in the fifth round of the NFL draft.

He signed with Green Bay, was cut in training camp, and spent the 1964 season on the Dallas Cowboys’ taxi squad before an injury ended his professional career.

He never appeared in a regular-season game, so the Chiefs’ claim on him stayed on the draft board rather than the roster. Even so, Kansas City’s selection of him that spring was a bet on one of the most reliable winners in college football.

Emmet Augustus “Duke” Carlisle III was born December 13, 1941, in Kaufman, Texas, and grew up in Athens. Under Darrell Royal at Texas he became the quarterback of the 1963 Longhorns, a team that finished 11-0 and claimed the program’s first national championship.

He was an Academic All-American and played both ways, lining up at safety when Royal needed him. Late in a 7-0 win over Baylor he intercepted a pass in the end zone to preserve the unbeaten season.

On New Year’s Day 1964, in the Cotton Bowl, Carlisle outplayed Heisman Trophy winner Roger Staubach.

He threw for a then-bowl-record 234 yards and two touchdowns, added 267 all-purpose yards, and led Texas to a 28-6 victory over Navy. He was named the game’s most valuable player.

That performance, weeks before the AFL draft, is what put his name in front of Lamar Hunt’s franchise as it built toward the teams that would win Super Bowl IV.

After football, Carlisle earned an MBA at Texas, worked as an investment banker in New York, and later settled into the oil business.

He was inducted into the University of Texas Athletics Hall of Honor in 1974 and the Cotton Bowl Hall of Fame in 2000.

He is survived by his wife of 62 years, Emily Alford Carlisle; daughters Kathy Carlisle Asher and Eloise Carlisle Terry; and his brother Todd. His nephew, Cooper Carlisle, later played in the NFL.

For the Chiefs, Carlisle remains a footnote of the 1964 draft, a player the club wanted and never got.

The organization joins Texas and the rest of the football world in remembering a quarterback whose defining afternoon came against the best player of his era, and whose name still sits in the AFL draft record beside Kansas City’s.
