Broadneck played its first varsity football season a year ago and lost all 10 games. Those memories were forgotten last Friday night, though, when the Bruins beat visiting Andover, 7-0, in an Anne Arundel ABC League game.

Ted Simmons caught a four-yard touchdown pass from Ron Smith in the second quarter and the Broadneck defense, aided by three pass interceptions, made it stand. New Coach Grant Jones couldn't have been happier.

"The players never gave up last season and had a good feeling about themselves afterwards," said Jones, who coached Chesapeake the past two years before succeeding Bruce Villack, now a Broadneck assistant. "They worked hard over the summer and in practice. Friday night it all paid off.

"The first year for a school is always tough, but what we learned last year made the difference against Andover."

Anthony Johnson, Chris Green and Billy Mays intercepted passes for the winners, turnovers caused in part by the pass rush of ends Jamie Farghar and Lonnie Sheppard. After Mays' interception with less than three minutes remaining in the fourth quarter, the offensive line, led by center Tony Campbell, gave running backs Scott Savelski, Tom Probst and Sheppard plenty of room to run out the clock.

Its recent jump from Class C to Class A, because of last year's state reclassification, might preclude a winning season for Broadneck, but the word is out. The Bruins aren't pushovers any more.

Prince George's County lost one of its top basketball coaches last week when Gwynn Park's Owen Johnson resigned because of a new teaching schedule that conflicted with practice times. Because Gwynn Park Junior High became a middle school this year, Johnson spends part of the day teaching at Oxon Hill Middle School. The traveling time wouldn't have allowed him to begin practice bewfore 4:30 p.m. and that was unacceptable to Johnson, who coached the Yellow Jackets to the state Class A championship last season.

His two-year record at Gwynn Park was 34-15.

Judi Hare, perhaps the best three-sport girls athlete in Montogmery County last season, will not return to compete in basketball, track and volleyball for Springbrook. Instead, she finished her high school courses over the summer and is attending Brigham Young University.

Top individual performances: Whitman quarterback Anthony Dilweg completed 20 of 34 passes and threw for four touchdowns to lead the Vikings to a 33-29 upset victory against Springbrook; Woodward's Jimmy Sood kicked the winning 27-yard field goal in his team's 9-6 overtime victory against Einstein and punted for a 48-yard average, including a 68-yarder; Potomac defensive lineman Kevin Love made nine tackles in a 12-6 overtime loss to Eleanor Roosevelt; Magruder safety Tommy Dean had two interceptions and nine tackles to lead the Colonels past Sherwood, 12-0; Bowie's David Brooks rushed for 203 yards and one touchdown to lead the Bulldogs to a 35-12 victory against Bladensburg.

Hammond won the Maryland state Class C boys basketball championship last season and was a strong preseason pick for this year's Class B title. But the Golden Bears were hurt by the transfer of forwards Perry and Terry Dozier, 6-foot-8 twins, to Baltimore's Dunbar High School. The Poets, the nation's top-ranked team last season, will play De Matha at Georgetown University Dec. 1.

Continuity in coaching makes the difference in high school sports. Jim Fegan has been football coach at Georgetown Prep since 1961 and hasn't had a losing season in 22 years at the Rockville private school. Fegan notes that assistants Frank Gilmore and Franny Gleason and Charles Keegan, the team physician, have also been there for more than two decades.

Former Potomac baseball Coach Charlie Sullivan will be the new coach at De Matha. One of Prince George's County's most respected coaches before being RIFfed last year, Sullivan, a De Matha graduate, will have designated hitter Darrin Campbell, an all-Met selection last year, among the players returning from a 12-5 team. Former coach Vince Kerley will remain as an assistant.

An insurance plan designed by a University of Virginia law professor is helping athletes who suffer disabling injuries pick up the pieces and go on with their lives.

The plan, a $10,000-deductible, no-fault insurance policy created by Jeffrey O'Connell, a law professor, is offered through the National Federation of High School Athletic Associations.

It has been adopted for the current academic year by high school athletic conferences in 48 states.

At the same time, the insurance plan protects high schools from financial hardship or even insolvency in the event of a successful lawsuit against them.

Above the $10,000, the plan provides for such things as medical and rehabilitation expenses, transportation costs and costs of remodeling the family home to accommodate a wheelchair. Wages lost by parents who have to take off work to help care for the injured athlete are also covered.

The policy also specifies it will give up to $300 of income each week for life if the recipient has less than $300 of income from other sources.
