Favorite: Douglass (12-2)

Despite the loss of WR Paul Harris to the University of Tennessee, it’s hard to bet against Douglass, particularly when second-year starting QB Devin Butler took them to the state title game as a freshman in 2012.

Contenders: Gwynn Park (10-2); Potomac (Md.) (8-3); Friendly (6-5)

Around the league: The Eagles’ defense, led by DT Gary Gross, LB Malcolm McCoy, and CB Devonta’ High, could be dominant. . . . Gwynn Park will have to find some playmakers to help out returning starter QB Jay Adams after losing leading rushers Marc Bronson and Joseph Hayman to graduation . . . Talent-laden Potomac may be ready to jump into the Prince George’s elite, thanks in part to a defense that features LB Jerome Dews, who’s made an oral commitment to Tennessee, and junior DT Keiron Howard, who’s garnered Football Bowl Subdivision attention. . . . Forestville (6-5) also looks poised to make a move with a roster that is low in numbers but high on talent. DB Marcel Joly has offers from a handful of Football Bowl Subdivision programs and Omar Geronimo, a 6-4 wide receiver/tight end, has the size and skill to be one of the premiere offensive weapons in the county . . . Opponents will likely struggle to score against Friendly, which returns its entire secondary and some big pieces on the line. Stanford-bound DB Alameen Murphy will lead the way for the Patriots, and is joined in the defensive backfield by Ravon Davis, who’s caught the eye of programs such as Temple and Coastal Carolina. . . . Don’t count out Largo (6-4), and new Coach Derron Thomas, who served as the team’s defensive coordinator last year. Thomas inherits a young team with big scoring potential in an offense anchored by senior lineman Marcus Bullock and senior wideout Josh Washington.
