Favorite: Yorktown (12-1)

Two-time defending National District champion is poised to continue success that’s yielded consecutive 12-win seasons.

Contenders: Edison (5-6); Hayfield (7-3); Mount Vernon (4-6)

Around the league: Yorktown features one of the area’s top players in All-Met running back M.J. Stewart, who rushed for 1,842 yards and scored 36 times. The UNC commit’s performance on offense and in the secondary will be even more important with the graduation of FB Arturo Brown and top LB Tyler Donnelly. Back is senior QB Will Roebuck, who spreads the field well with a variety of passes and positions the Patriots for another deep playoff run. . . . Hayfield returns 13 starters, three of which are skill players with playmaking ability. Offensively, three-year starting QB Ellis Knudson and RB Osman Kargbo give the Hawks a formidable one-two punch while all-region linebacker George Asante excels as a tackler. . . . Edison is anchored by QB Harrison Dandridge, who passed for 1,619 yards and a region-high 20 touchdowns last year. Since the senior’s favorite target, LaSalle Mensah, graduated, Dandridge hopes to build new chemistry with WR/DB Ricky Todd. Joining Todd in the secondary is all-district junior Schylar Johnson. Mammoth tackles Robby Baird (6-3, 295) and David Beinhart (6-7, 325) are ones to watch. . . . Mount Vernon’s Carlton Griffith looks to build on a huge junior campaign that yielded 1,671 rushing yards and 12 TDs in hopes of ending the Majors’ four-year playoff drought. . . . Falls Church stands as the dark horse, thanks to the return of QB Adam Daly and RB Dieon Dupont.
