McNamara and Madison were originally scheduled to play near the end of the season. But because of scheduling conflicts the schools squared off yesterday. Maybe Madison should have waited.

The overmatched, undersized Warhawks gave a valiant effort but were defeated by 10th-ranked McNamara, 33-18, in the teams' season openers at McNamara.

This was one of the rare times that a Virginia public school crossed the state line to play a Maryland school. The matchup was made possible when Centreville added a varsity team to the Northern Region this season, giving Virginia schools an extra game to fill.

McNamara Coach Tom Clark added something to his program as well. His version of the no-huddle, run-and-shoot offense was unveiled yesterday and looked devastating at times. "I was pretty pleased with it," he said. "We have good personnel at key positions to be able to do it."

Behind senior quarterback Junior Bynum, the Mustangs won their first season opener in three years. Bynum had 255 yards and two touchdowns passing, and he scored the other three touchdowns on runs of four, one, and one yards.

McNamara ran the ball only 10 times the entire game; three of those were from the 1 and three others were to run the clock down on the last possession.

Bynum was a reserve behind Asim Penny last season, but the 6-foot-5 Penny was moved to wide receiver this year to make room for Bynum.

"He's still learning," said Clark. "But he's a heck of an athlete."

Bynum had some problems in the first half. He completed six of 19 passes and had three interceptions. But on McNamara's second possession Bynum hit senior fullback Afiba Fairnot for a 26-yard gain to the Warhawks 15. Fairnot gained 11 yards to the 4 on the next play and Bynum ran in from there. Tony Robles made it 7-0.

But Madison's undersized line surprised the Mustangs on its possession and put together a 13-play, 80-yard drive capped by John Hardy's seven-yard scamper. Hardy was the mainstay of the Warhawks' offense as he carried 18 times for 109 yards and two touchdowns. He also caught a 45-yard touchdown pass from Kevin Solan near the end of the game.

Solan showed patience while completing 14 of 28 for 162 yards. His eight-yard dump pass to Brian Holtorf set up Hardy's 19-yard gain to give Madison a 12-7 lead with 10:41 left in the half.

But McNamara came right back and, despite penalties, regained the lead when Bynum hit Keith Warren from 28 yards. Bynum's pass failed on the extra point and the Mustangs led, 13-12, at halftime. Madison (0-1) 6 6 0 6 18 McNamara (1-0) 7 6 7 13 33 SCORING
