Skinny: Damascus’s size will present a problem for opponents this winter, as the Swarmin’ Hornets return one of the league’s best players in 6-3 junior Kelli Prange (16.2 ppg) , and a pair of 6-1 posts in Becky Barrett and Lauren Derby, a core of players who should complement junior guard Jenna Kaufman. . . . Poolesville has six of its eight top scorers back, including senior guards Kelsey Carnahan (5.8 ppg) and Kelly Hughes (8.2 ppg), who will have to pick up the offensive production created by graduated senior Lindsay Poss (19.8 ppg in 2011-12) . . . First-year Seneca Valley Coach Katie Caldwell expects several seniors on her roster to step up and fill the roles of departing seniors Bridget Rothert and Sasha Orr, who accounted for nearly all of the Screaming Eagles’ scoring a year ago. Cadwell said senior forwards Taylor Winbush-Drew and Charlotte Cunningham will have a key impact on the perimeter. . . . Watkins Mill is expected to be improved from last season’s 13-11 finish, and have talented young guards in Dominique Walker (11.2 ppg) and Danielle Durjan (7.3), who picked up valuable experience as freshmen last season.
