It starts with their puck management and puck support, because far too often in the first two games the Lightning were the givers, fueling the Penguins' speedy attack with turnovers.
It's not a fluke they were outshot 76-41 in Pittsburgh. It might, however, be somewhat of a fluke they scored five goals, if you believe in the theory Murray belongs in the Conn Smythe Trophy discussion as the best player in the playoffs.
Murray has an .878 save percentage in two games against the Lightning; he combined for a .935 save percentage in nine games against the New York Rangers and Washington Capitals. He has looked shaky at times, so much so Penguins coach Mike Sullivan probably would have turned to Marc-Andre Fleury if Murray allowed a third goal before the third period in Game 2.
Murray didn't, but it's not as if the Lightning tested him or Sullivan's belief in him a great deal. They were outshot 27-13 after the first period, including 16-6 in the third and 3-0 in overtime in Game 2. They were outshot 16-5 in the third period of Game 1, although the Penguins were chasing a two-goal deficit.
Cooper went as far as to admit puck possession, or lack thereof, is a concern for the Lightning, who typically thrive as a puck possession team.
"We have put ourselves in position to have the puck more, but we're not being very smart with how we're playing," Cooper said. "We're not playing as a group of five on the ice. We're in all different segments, playing in different zones, changing when we shouldn't. When you're not in unison, you're not going to have the puck."
