"Football is 22 people on the field who need rest…

In spectator sports, the athletes get all the exercise and the spectators get all the rest. “Football is 22 people on the field who need rest and 22,000 people in the stands who need exercise” is a statement of uncertain origin. “Twenty-two boys on the field badly in need of rest, and 40,000 people in the stands badly in the need of exercise” was said in 1963 by Bud Wilkinson (1916-1994), the head football coach at the University of Oklahoma who served on the President’s Council on Physical Fitness. Wilkinson popularized the saying, but didn’t coin it.

“We still have 50,000 people in the stands who need exercise, and 22 boys down on the field who need rest” was cited in print in 1959.

Wikipedia: Bud Wilkinson
Charles Burnham “Bud” Wilkinson (April 23, 1916 – February 9, 1994) was an American football player, coach, broadcaster, and politician. He served as the head football coach at the University of Oklahoma from 1947 to 1963, compiling a record of 145–29–4. His Oklahoma Sooners won three national championships (1950, 1955, and 1956) and 14 conference titles. Between 1953 and 1957, Wilkinson’s Oklahoma squads won 47 straight games, a record that still stands at the highest level of college football. After retiring from coaching following the 1963 season, Wilkinson entered into politics and, in 1965, became a broadcaster with ABC Sports. He returned to coaching in 1978, helming the St. Louis Cardinals of the National Football League for two seasons. Wilkinson was inducted into the College Football Hall of Fame as a coach in 1969.

A Generation of Spectators
The major indictment of football today is that too few participate, according to Herman Hickman, former coach at Wake Forest, North Carolina State, West Point and Yale. Today’s subsidized varsity puts on a weekly show for the 99 per cent of the student body in the stands who need exercise.

The vast difference between the physical quality of the athlete and the physical quality of the spectator was pointed out in an address by the President in April, when he quoted an acquaintance’s comment about a Harvard football game: “Twenty-two boys on the field badly in need of rest—and 40,000 people sitting in the stands badly in need of exercise.”

(By Carl F. Henry, editor of Christianity Today)
Christianity has often been labeled a spectator sport. One wag went a step further by facetiously comparing the Church of the 1960s to a hard-fought football game: eleven men on the field who need a rest and fifty thousand in the stands who need the exercise.

“In these worldwide problems we are too often spectators. The church reminds me of the crowd at a good football game. There are people watching in the stands who need exercise, while 22 men playing on the field need rest.”

Bud Wilkinson, famed former coach of the Oklahoma University football Sooners, was asked during a speech in Dallas to describe football as a game. “The game of football,” he replied, “may be described as a game in which there are 22 men on the field who desperately need rest and about 40,000 people in the stands who desperately need exercise.”

Cooper’s (Dr. Kenneth Cooper—ed.) presentation was often humorous and he used football fans to point out one of the ironies of present-day America.

“It’s a situation where you’ve got 22 men on the field in desperate need of rest and 65,000 fans in the stands who desperately need exercise.”
