Fleury hasn't played since Game 3 of the Eastern Conference Final, when he allowed four goals on nine shots in 12:52 before Murray replaced him. Going into Game 3, Murray was 5-1 with a 1.54 goals-against average and .943 save percentage in the 2017 Stanley Cup Playoffs.
In his past two games, Murray's GAA has gone up to 2.08 and his save percentage has dropped to .925.
"Like anything, we make our lineup decisions on a game-by-game basis," Sullivan said. "The one comment I will make is we didn't lose the game [Monday] night because of our goaltending."
But you can make the case the Predators won Game 4 because of their goaltending.
Pekka Rinne was outstanding with 23 saves on 24 shots, many from directly in front of him, including some off breakaways or chances generated after the initial save on a breakaway.
If Rinne is going to be that good, the Penguins are going to need their goaltending to at least match him. Murray didn't do that, but he didn't get much help either.
Sullivan, in fact, traced that back to the past two games, when he said there were some goals the Penguins allowed that were preventable. There is no debating him on that, and it's a reason why Murray deserves a partial pass.
Predators defenseman Roman Josi scored a power-play goal at 5:51 of the second period in Game 3 on a shot deflected by Penguins forward Carter Rowney's left hand; Rowney was too late getting into the shooting lane to make the block.
