Washington tied up one of its many offseason loose ends Tuesday, extending its affiliation with the American Hockey League’s Hershey Bears through the 2014-15 season. Next year will mark a decade of partnership between the teams, which both face pivotal summers after failing to reach the playoffs. “The Bears are a great franchise and we look forward to working together again to develop our prospects in Hershey,” Capitals president Dick Patrick said in a news release. The height of the Capitals-Bears relationship during this agreement came as the NHL team rebuilt and stocked the AHL pipeline with top young players. Several who were groomed in Hershey and experienced a Calder Cup championship in 2006, 2009 or 2010 have gone on to become NHL mainstays, such as John Carlson, Karl Alzner, Brooks Laich, Eric Fehr, Boyd Gordon (now in Edmonton), Tomas Fleischmann (Florida) and Michal Neuvirth (Buffalo).
