In his first day on the job, West Hall’s Tony Lotti decided he needed to do a little decorating around his fieldhouse office.It was a brisk day in January 2012 when Lotti, fresh off a move with his family from Stockbridge, hung a square, black picture frame on a wall close to the team’s meeting room. It has stayed empty for more than two and a half years. “They all know it’s there,” Lotti said, before his team’s Thursday walkthrough on Spartan Field.
