BREWER, Maine — One of the youngest lineups in Class A boys basketball this winter is being fielded at Brewer High School, with one sophomore and two freshmen among the Witches’ starting five. Such lineups typically endure growing pains while also experiencing significant improvement, and coach Ben Goodwin’s club is no exception as it prepares for the final third of its regular-season schedule. Despite a 62-46 loss to defending regional champion Hampden Academy on Thursday night, Brewer has won four of its last seven games after a 1-5 start.
