The line of Pacioretty (four goals, six assists), Paul Stastny (two goals, six assists) and Mark Stone (six goals, four assists) combined for 28 points (12 goals, 16 assists) in the first four games of the series.
But they were held without a point in Games 5 and 6. Pacioretty scored in Game 7 and Stone had two assists, but that line was a combined minus-8 in the final three games of the series.
"We obviously knew that this would be a series that would take a lot to win right until the very end," Pacioretty said. "Obviously we think we had the game in the bag, the series in the bag. It is a frustrating feeling, but we have to remember it for next year."
