Favorite: Flint Hill (7-2)

The defending champion Huskies have double or triple the number of players as their MAC rivals, and have separated themselves from the rest of the league. But anything can happen in the MAC, where one conference loss normally takes a chance at a title off the table.

Contender: Potomac School (5-4)

Around the league: Flint Hill will need all of its numbers to reload after losing starting QB Stevie Peterson and leading rushers Connor Chess and J.J. Becker to graduation. . . . The Potomac School returns several offensive weapons from a team whose only conference loss in 2012 came to Flint Hill. . . . Maret ’s starters should match up well with everyone in the MAC — at least in the first quarter — but limited numbers will require almost everyone to play both ways, so their season will pivot on good health and stamina. The Frogs (4-5) boast a Football Championship Subdivision prospect in lineman Jeremy Zeitler, and senior quarterback Marco Tornillo provides a consistent offensive threat. . . . Sidwell Friends (6-3) also makes up for what it lacks in numbers in two-way talent, led by versatile LB/TE and occasional lineman Niles Brown and WR/DBs Oscar Boochever and Diamente Holloway.
