By Kevin Dillon/DFP StaffBefore the Boston University men’s hockey team fell to No. 17 University of Vermont 6-2 at Agganis Arena Saturday night, there was already some activity in the news conference room. This press conference was not between the collected media and BU coach David Quinn like it usually is, but instead it was between a youth hockey goaltender and his father.The son sat tall at the microphone, wearing his team’s jersey and fielding questions from his father who pretended to be a media member. It was a chance for the boy to dream he played goalie for the Terriers, and he smiled wide during each answer he gave his father.Later in the night, the boy sat in the stands and watched senior goaltender Anthony Moccia finally get his chance to live that dream. The Medford native, who spent a year as a practice goalie, walked on to the team and is now in his third and final season as a third-stringer, got between the pipes in front of 4,948 fans for his first regular-season action.“It’s kind of always been a huge goal of mine to play in a regular season game and I was able to get in there today,” Moccia said. “I can check that off the list of things that I have to do.”For more, visit www.dailyfreepress.com.
