• Martin Havlat's second goal of the game earned the Sharks a 3-2 double-overtime win in the opening game of their series against the Blues. All seven of the Sharks' playoff series openers over the last three years have been decided by a one-goal margin, including three in overtime. In fact, 13 of San Jose's last 15 Game 1s were one-goal games (six went to OT), and the two games that didn't fit the pattern were 2-0 final scores.
• The Bruins' victory against the Capitals marked only the eighth time in NHL playoff history that a team posted a 1-0 overtime win in the first game of a playoff series. It was the second such win by the Bruins, who posted a 1-0 double-overtime victory in Game 1 of a best-of-five series against the Maple Leafs in 1935.
Chris Kelly's goal 78 seconds into overtime gave the defending Stanley Cup champion Bruins a 1-0 win in their 2012 playoff opener against the Capitals. Kelly's name in the goal column of the scoring summary was a guarantee of a Bruins victory during the regular season. Boston won all 18 regular-season games in 2011-12 in which he scored. Kelly's 20 goals this season made him the only one of the 246 NHL players with a double-figure goal total in the 2011-12 campaign who scored all of his goals in games his team won.
• The Bruins, Sharks and Coyotes all won in overtime on Thursday. It marked the first time since April 18, 2001, that 3 NHL playoff games went into overtime on the same day.
• The Rangers' top three goal scorers during the regular season, Marian Gaborik (41 goals), Ryan Callahan (29) and Brad Richards (25), each scored a goal in the Blueshirts' 4-2 victory in Game 1 of their first-round playoff series against the Senators. Gaborik, Callahan and Richards scored goals in the same game only twice during the 2011-12 season: Oct. 29 versus Ottawa and Nov. 29 against Pittsburgh.
