FILE - In this March 20, 2016, file photo, Pittsburgh Penguins' Kris Letang (58) checks Washington Capitals' Alex Ovechkin (8) off the puck during the first period of an NHL hockey game in Pittsburgh. The Capitals and Penguins are almost unchanged from their playoff meeting a year ago, but the small differences could make a major impact in their second-round series. Pittsburgh doesn’t have defenseman Kris Letang, while Washington has added depth in center Lars Eller and defenseman Kevin Shattenkirk that makes it think it can topple the defending Stanley Cup champions.
