It Takes a Man to Play Defense Chester Fritz played tackle for Don Faurot at Missouri, went in the first round to the 49ers, and won two pro championships in Richmond before he coached Hermitage High School for 21 seasons. The defensive beliefs he put on paper still read like a clinic. NOTES BY COACH CHESTER E. FRITZ · INTRODUCTION AND DIAGRAMS BY AFQ STAFF Long before anybody kept a spreadsheet, Chester Fritz kept score on his defense. Two interceptions in every thirteen passes thrown.

Twenty yards on every return. Three and a half fumbles forced a game, two and a half recovered. Make the other team snap the ball twelve times, and if they haven’t scored, they have been stopped. It reads like an analytics deck, and it came from a man who played his football in the 1940s. Fritz had earned his opinions.

He was a first-team all-conference tackle at Missouri under Don Faurot, the father of the split-T, and the seventh player taken in the 1949 draft of the All-America Football Conference, by the San Francisco 49ers. Drafted by Washington of the NFL as well, he signed instead with the Richmond Rebels, the Chicago Bears’ farm club, and the 1949 Rebels gave up 99 points in ten league games on the way to the American Football League title. They won it again in 1950.

Then he crossed town to coach, and for 21 seasons at Hermitage High School—including a 10-0 state championship season in 1958 that he called “a team of a lifetime”—his Panthers played the kind of defense these notes describe. The pages that follow are his. They come from a handout of Fritz’s defensive notes, and we have reproduced them the way he organized them, with only light copyediting.

Some of it is bound to its era—no one is holding a 2026 secondary to two picks in thirteen attempts—but the architecture underneath is not. Morale first. Everything is pass defense. Two units with two jobs: one that never varies and forces nothing, one that gambles because the other has its back. Twelve snaps. Six men to the ball. The diagrams are ours, drawn to his words rather than from his playbook. The words are his. FROM THE ARCHIVES FROM THE ARCHIVES

WHY DEFENSE IS THE MOST IMPORTANT PART OF FOOTBALL 1. If the opposition doesn’t score, you can’t lose. 2. If your defense is tough enough, the opposition can’t score. 3. You may have the best offensive team in the business, but you can’t use it until you get the ball. THE MUSTS OF BUILDING A DEFENSE 1. Morale. The most important factor. Sell your players on “slowing up” the offense. 2. All defense is pass defense. The pass is the atomic bomb in football.

Very, very seldom do you get run over; it is the pass that kills you. There are few games lost which would not have been lost if it hadn’t been for the pass. Thus the belief: everything is pass defense. 3. Prevent the “easy” scores. In conjunction with the plan to slow up the opposition, make them put the ball in play 12 times. If at this point they have not scored, then they have been stopped—they will never score. After this point all the percentages go over to the defense.

The basis for this assumption is that they cannot put the ball into play many more times without making a mistake themselves: backfield in motion, offsides, a fumble, an overthrown pass, and so on. If none of this happens, assume that you will be playing the type of defense that sooner or later makes an exceptionally good play which completely throws the opposition for a loss.

In slowing up the opposition, you are trying to put them in the “6-yard situation”—that is, placing them in a position where they must average 6 yards per try for the first down. UNITS OF THE DEFENSE A good defense is composed of two units: the containing portion and the forcing portion. 1. Containing portion. Never—never—varies. It is played the same way every time. The reason for this is the belief that if no mistakes are made in this area, no easy scores will be achieved by the opposition.

Keep the ball in front of you and inside of you, and NEVER make an aggressive move. This unit forces nothing. · SEPTEMBER 2026 · SEPTEMBER 2026

14 2. Forcing portion. Constant variations—the element of surprise. With this unit a gamble can be risked, because if an error is made there is still the containing unit to back them up, and the error doesn’t result in a touchdown. This unit attacks when the ball is snapped; they try to do something to create an error on the part of the opposition, thus the need for varying tactics. Figure 1. Fritz’s two units, shown on a 1950s Oklahoma 5-4 front.

The forcing unit (red) attacks at the snap and never does the same thing twice; the containing unit (navy) never varies, keeps the ball in front and inside, and forces nothing. Fritz described the units by their jobs rather than by position, so the assignments here are illustrative. OBJECTIVES 1. Primary objective. Keep the opposition from scoring. Work on the theory that if the opposition does not score, you will not lose. Do not allow the opposition to score on your goal line. 2. A sound kicking game.

Be able to kick the ball out of dangerous territory. If a team can do this and eliminate the “easy” touchdown, the opposition will stop itself 65% of the time through offensive mistakes. Have an aggressive defense. 3. There are more ways to score while on defense than there are on offense; thus the odds favor the defense. Sell your team on this idea. Playing defense is the toughest assignment in football. In order to do this, however, there must be good team morale.

Figure 2. The containing rule against a sweep. The end squeezes without attacking and the halfback stays outside and in front of the ball, so the runner is turned back inside— into the pursuit of the forcing unit. DEFENSIVE AXIOMS There are certain “musts” that have to be considered if the defense is to be sound: 1. Do not allow the opposition to complete a long pass for the “easy” touchdown. 2. Do not allow the opposition to make a long run for the “easy” touchdown. 3.

Do not allow the opposition to score by running from within your 5-yard line. 4. Do not allow the opposition to return a kickoff for a touchdown. 5. Do not allow the opposition to average more than 20 yards per kickoff return. 6. The defense must intercept 2 passes out of every 13 attempted. 7. The defense must average at least 20 yards on each interception. 8. The defense must return 3 interceptions per season for touchdowns. 9.

The defense must force the opposition to fumble the ball on the average of 3½ times per game. 10. The defense must recover an average of 2½ fumbles per game. IMPORTANT THINGS TO BE TAUGHT IN OUR DEFENSE 1. Gang tackling. There should be 6 or 7 players in on every tackle, to demoralize the

16 ball carriers and wear them down physically as well. The first tackler should get a good shot at the ball carrier—do not miss him—and hold him up; the other players tackle the football and unload on the carrier. You must get possession of the ball, and it is (practically) impossible for any ball carrier to break loose and score when half a dozen players are fighting to get a piece of him. 2. Defensive stance 3. Surprise defense 4. Victory defense 5. Goal line defense 6. Defense of options 7.

Defense of unbalanced lines 8. Stunting system Figure 3. Gang tackling as Fritz taught it: the first man gets a good shot and holds the carrier up; the next five or six tackle the football. Items two through eight were headings only in the notes we have; the teaching lived on the practice field at Hermitage. Fritz’s last line is the one his players still quote, and it is the only one that needs no diagram. “Anybody can play offense, but it takes a MAN to play defense!” —Coach Chester Fritz

WHO WAS COACH FRITZ Chester Eugene Fritz was born February 17, 1921, in Warrenton, Missouri, and played his high school football in Fulton, Missouri. He entered the University of Missouri in 1941, left for four years in the U.S. Navy during World War II, and came back to letter for Don Faurot’s Tigers from 1946 to 1948, earning first-team all-conference honors at tackle in 1947 and 1948 and All-America recognition as a senior.

In the 1949 drafts he went seventh overall to the San Francisco 49ers of the All-America Football Conference and in the seventh round to the Washington Redskins of the NFL. He signed instead with the Richmond Rebels of the American Football League, a Chicago Bears affiliate, in August 1949, and played tackle and guard on the league’s last two champions, in 1949 and 1950.

After a season as assistant line coach at the University of Richmond in 1951, Fritz joined Henrico County’s schools at Glen Allen High School, the forerunner of Hermitage High. He spent 34 years there as a physical education teacher and athletic director and 21 as head football coach. His 1958 Panthers went 10-0, closed with a 52-0 win at Parker Field and were awarded Virginia’s Group I championship—there were no playoffs—on Thanksgiving night.

A retrospective national ranking of the 1958 season put Hermitage 11th in the country. Peers called him an innovator: he brought the split-T to the Richmond area and built, with his principal, the first isometric conditioning program for high school athletes in Virginia. He is a member of the Virginia High School League Hall of Fame, the Hermitage High School Hall of Fame and the Fulton High School Wall of Fame, and Hermitage named its stadium for him in 1982. Chester E. Fritz Stadium is still home to the Panthers.

“Chief” died in Richmond on December 30, 2002, at 81. Coach Fritz’s defensive notes appear courtesy of TK. Diagrams are AFQ illustrations of the principles in the notes, not reproductions of Fritz’s playbook.
