ANNAPOLIS. MD. – Let’s hope that Navy ‘s national defense is not as bad as their hockey team’s. Delaware hockey crushed the United States Naval Academy 5-2 last Saturday in American Collegiate Hockey Association action. The Hens ( 12-9-1) dominated a game in which they outplayed and embarrassed Navy at their home arena, Dahlgren Hall. The Midshipmen (5- 13-2) were turned into more roadkill for Delaware, who are 7-2-1 away from home.
