Loudoun Valley (4-3) at Park View (7-0)

Friday, 7:30.

Last meeting: Sept. 8, 1995. Loudoun Valley won, 14-13.

Key for the Vikings: Possession time. "When we get the ball, we need to be able to keep it," Loudoun Valley Coach Mike Barton said. That might be difficult, as Park View has been shutting down its opponents' running games lately. "We've shown that we can run the ball against a tough defense," Barton said. "Is Park View a step above? I guess they are. But I still think there are some things that we can do on offense to move the ball against them."

Key for the Patriots: Score early, to force Loudoun Valley to put the ball in the air. Because tailback Ben Cross is the Vikings' strength, Loudoun Valley won't want to do that--but the Vikings will need to if Park View's offense puts them in an early hole.

Notable: Loudoun Valley quarterback Grant Harris attempted just two passes, and completed none, in last week's 42-0 win over Broad Run.

Liberty (1-6) at Loudoun County (5-2)

Friday, 7:30.

Last meeting: Oct. 19, 1998. Liberty won, 28-21.

Key for the Eagles: Tackling on the defensive line. Liberty has the same kind of big, physical defense as Handley, which handed the Raiders a 28-7 loss last week. Loudoun County doesn't have a big line, so the Eagles should be able penetrate and get into the Raiders' backfield. But Liberty Coach Joe Trabucco points out that his secondary players lead the team in tackles. If that's the case again Friday, the Eagles could be in big trouble.

Key for the Raiders: For the offense to score early. "We're not very good when we're behind, that's well known," Coach Pat McManus said. "We've got to find a way to move the ball and keep the ball, and then produce points."

Notable: The visiting team has won three out of the last five games between these two teams.

Handley (6-1) at Broad Run (2-5)

Saturday, 1:30.

Last meeting: Sept. 1, 1995. Handley won, 14-2.

Key for the Spartans: Execution on offense. Broad Run has been shut out in each of its five losses but scored 40 combined points in its wins over Colonial Forge and Warren County. "We've been close on offense, but it's just been a matter of one or two players not making the right play," Coach Ken Belchik said.

Notable: Junior Jacob Davis has rushed for 200 yards in three games since returning from a torn knee ligament that forced him to miss three games.

Warren County (3-4) at Potomac Falls (4-3)

Saturday, 1:30.

Last meeting: None.

Key for the Panthers: Stop the run. Potomac Falls has yielded at least 120 yards rushing in all three of its losses this season, including 369 in a 41-0 loss to Park View last week. Meanwhile, Warren County senior Brad Keller had 205 rushing yards and five touchdowns, and teammate Travis Diamond added 98 yards and one touchdown in Friday's 42-28 win over Liberty.

Notable: This is the first meeting between the teams. Potomac Falls is in its first season playing in the AA Northwestern District, after playing AAA for its first two years.

Fauquier (3-4) at Stafford (3-4)

Friday, 7:30.

Last meeting: Not available.

Key for the Falcons: Control the line of scrimmage on both offense and defense. If Fauquier can move the ball on offense and contain Stafford's running game, Falcons Coach Tom Ferrell thinks his team stands a good chance. "If we don't control the line of scrimmage, it could be a long night," Ferrell said.

Notable: Fauquier will be missing junior right guard Alex Crea, who is out for the year with a broken wrist suffered two weeks ago against James Wood. Junior defensive back Derrick Bragg is out with a knee injury but could return later this season.
