The Dulles league will start out as a two-way race between Western Loudoun neighbors Loudoun Valley and Heritage. The Vikings feature the league’s best player in Rowley, a William & Mary signee who average 16.6 points per game last season and set a school record with 10 blocked shots in a game. His ability to get to — and defend — the rim, will be central to Valley’s drive for a state tournament run. . . . Heritage features a dynamic backcourt duo in in Jesse Case and Zach Coffman, but figures to also receive production from juniors Morris Robinson and Josh Anderson. Indiana transfer Cole Miller is someone first-year Coach Rob Smart thinks can contribute as well. . . . Dominion will look to replace last year’s production from Lael Davis, who transferred to The Miller School. The Titans will turn to seniors Tony Richardson and Evan Ferguson to lead this team. . . . Loudoun County graduated nine players from last year’s team that finished 17-9. Senior Tim Herring will lead the Raiders, with expected contributions coming from senior Luke Adams, senior Ian Dillingham and junior Quad Borup. . . . In its second year, Champe returns sophomore Zachary Burdick (10.5 ppg) and junior Steven Baker (10.3 ppg). . . . After graduating eight seniors, Park View will turn to guard James Zentz to lead the way. Basketball Preview
