THE ANNANDALE High School football statistic cheet does not include a column for listing mistakes. The Atoms simply don't make many.

By playing near-perfect football, Annandale has won more games than any other school in the Washington metropolitan area since 1970.

The Atoms have compiled an 83-18-1 won-lost mark for a winning percentage of .822. They have captured four Virginia AAA Northern Regional titles, two state titles and have been runners-up once.

Last season Annandale finished as the area's top-ranked team, winning the state crown and ending a dream year at 140.

Clearly, the Atoms have been the No. 1 local high school football dynasty of the '70s.

Annandale is considered the class team in the area by local high school and college coaches and other close followers of the game, but it does not have the best percentage.

Georgetown Prep has compiled a 61-11-4 record for a percentage of .857. Many of the victories were against schools in the small Interstate Athletic Conference before Prep, by mutual agreement, left the conference and went independent. Since leaving in '75, Prep has won 27 of 34 games (tying one) for a percentage of .818.

"Prep may have the best average or percentage around but they didn't have to look forward to the T.C.s(Williams) or the W.T. Woodsons every season," said one area coach. "I don't doubt Prep or Carroll are good teams but I just feel the competition in Northern Virginia is better year in and year out."

Annandale Coach Bob Hardage, the brains behind the Big Red Machine, would not compare the caliber of play in the area.

We've always been blessed with excellent football players," said Hardage. "And the kids always work hard. And I guess, it helps to have a little luck."

The remaining eight schools on the dynasty list are Carroll, T.C. Williams, Friendly, Gaithersburg, St. John's, Churchill, W.T. Woodson and T. Roosevelt.

The schools were selected on the basis of their won-lost records, caliber of competition and overall consistency against league and nonleague, teams since 1970.

Other schools with excellent percentages in the outlying suburbs are Woodbridge (65-26-2, .714) in the Virginia Commonwealth District, Howard (79-23-2, .774) in Howard County, La Plata (65-24-1, .725) in Anne Arundel County.

Teams in these jurisdictions have only recently begun to compete against D.C. area schools and thus were not considered for inclusion on the dynasty list.

Several other schools in the area have either had fine years in the early '70s or just begun to dominate their respective leagues lately.

Seneca Valley captured 31 straight games before losing last year. The 6-year-old school won two Maryland titles along the way.

Parkdale and Crossland took turns winning the Prince George's AA titles in the early to mid '70s before falling off. Crossland has just begun to come back, winning 17 games and advancing to the state playoffs the past two years.

Paint Branch, Anacostia, Springbrook, Eastern, Gar-Field and Fort Hunt have also been very consistent in the '70s.

Carroll (70-17-2, .805) has had only one losing season in the decade. The other years, the Lions were vying in the Metro Conference with St. John's. Ver that stretch Carroll won the title four times while finishing second three times. Last year, Coach Maus Collins had one of his better teams. The Lions went undefeated (10-0) and posted five shutouts.

Just a notch below Annandale in Northern Virginia is T.C. Williams. Under Coach Herman Boone, who was dismissed this year, the Titans won two regional championships and one state title. Williams didn't begin play until 1971 but has compiled a 65-18-3 mark for a percentage of .783.

Friendly (74-21-1, .779) has been the most consistent school among the area Maryland schools. The Patriots have won two Class A State crowns and been runners-up once.Coach Jim Crawford said that 1976 team, which finished 9-1 in AA competition but did not advance to the playoffs (lost to eventual state finalist Bowie, 7-0), was one of his better teams.

The defending A state champions have again been reclassified AA this season.

Gaithersburg (69-21, .766) is the only public school listed in the top 10 that has not earned a playoff berth. The Trojans, whether classifed AA or A, always come up a touchdown or field goal short of winning the Montgomery County championship. While in AA, the Trojans would inevitably beat eventual champion Churchill but lose to an also-ran along the way. Coach John Harvill has not had a losing season in more that a dozen years.

St. John's (66-23-3, .742) finished a disappointing 5-5 last season. In the previous four seasons, Dave Waldron's charges won 35 games and three Metro Conference titles.

Churchill (69-26-1, .726) took its lumps from 1970-72, winning only 16 of 30 games. The following five seasons, the Bulldogs dominated play in the Montgomery County AA. A total of 47 victories brought four straight trips to the playoffs and yielded two state titles. Last year Churchill limped home with a 6-4 record but don't expect Fred Shepherd's teams to lose often.

W.T. Woodson, Annandale and T.C. Williams have been involved in classics. When any pair of the teams meet, one can expect one of the better games of the year. Woodson (61-26-4, .701) has been remarkably consistent despite being denied the state playoffs recently, mainly because of the other two titans.

Theodore Roosevelt (63-27-3, .700) has been the most consistent team in the tough D.C. Interhigh League. Coach Jim Tillerson's teams, while winning the title four times in the last six years, must own the area record for endurance. The Rough Riders, because of ties, a make-up game and bad weather, were forced to play all or part of six games in 20 days to win the title in 1976. As the season wore on, Roosevelt got tougher, yielding but 20 points in its last five games.
