If only Games 3 and 4 of this series lived up to the billing that Game 5 provided. For almost 100 minutes Monday, the Boston Bruins and Tampa Bay Lightning played a hockey game befitting the two best teams in the NHL during the regular season. The two teams traded chances and the goaltending was outstanding as the second overtime period wound down in Game 5. Victor Hedman’s shot through a Pat Maroon screen evaded Jaroslav Halak for the series-clincher, spoiling Boston’s best effort since it won the first game of the series. The Bruins outshot the Lightning 47-35, but could not convert on their numerous chances in regulation and overtime to prolong their season.
