AAA Concorde District

Favorite: Westfield (12-1)

The Bulldogs graduated 43 seniors but have lost two or fewer games just seven times since opening in 2000, winning state titles in 2003 and 2007, and are again expected to contend.

Best rivalry: Westfield vs. Centreville
(Oct. 26)

Westfield opened in 2000, taking a chunk of Centreville’s population. Although Westfield has a 10-2 advantage in the series, the atmosphere at last year’s two games, including the Northern Region Division 6 championship, was unmatched in the region.

Players to watch: DB Andy Boone, Oakton (5-8, 160, Sr.); QB Kyle Downer, Oakton (6-2, 195, Sr.); RB DeAndre Harris, Chantilly (5-8, 155, Jr.); DL Jake Pinkston, Robinson (5-9, 240, Jr.); QB Sonny Romine, Chantilly (6-0, 175, Sr.).

AAA Liberty District

Favorite: Stone Bridge (10-2)

The Bulldogs have won at least 10 games in 10 consecutive seasons and have appeared in six of the past seven region championship games, winning five.

Best rivalry: McLean vs. Langley (Nov. 2)

Although neither team has made an appearance in a region title game since McLean in 1996, the two schools are separated by just four miles and draw heavy local crowds for their annual showdown.

Players to watch: DL Jonathan Allen, Stone Bridge (6-3, 245, Sr.); OL Burke Bartow, McLean (6-3, 340, Sr.); QB Ryan Burns, Stone Bridge (6-6, 230, Sr.); RB Rassaun Goldring, Stone Bridge (5-8, 155, Sr.); OL Jack Howerton, Langley (6-2, 320, Sr.).
