The Pittsburgh Penguins are halfway to becoming the first team to win back-to-back Stanley Cup championships since the Detroit Red Wings in 1997 and '98. Pittsburgh won Game 7 of the Eastern Conference Second Round on Wednesday to eliminate the Washington Capitals. If the Penguins are able to get past the Ottawa Senators in the Eastern Conference Final and defeat the Western Conference winner in the Cup Final, they'll end the longest stretch without a repeat champion in NHL history.
