But after winning Game 4 3-1 on Thursday to tie the best-of-7 series 2-2 entering Game 5 at Capital One Arena on Saturday (7 p.m. ET; NBC, SN, TVAS), the Penguins might finally have line combinations that click.
"A lot of it is just the gut instinct of the coaching staff on where we think our group is at," Sullivan said. "We've adjusted some line combinations. We've created some balance through our lineup. … We evaluate our lineup and our decisions after every game, and we try to put the best lineup on the ice that we think gives us the best chance to win."
Sidney Crosby centering the top line with Jake Guentzel at left wing has been the one constant for Pittsburgh this series. They've combined for 18 goals in the Stanley Cup Playoffs with everyone else combining for 20, or 12 without Patric Hornqvist's and Malkin's four goals each.
Crosby and Guentzel have controlled the puck for long stretches but have also generated off the rush. The rest of the lineup could ignite if it takes the same approach.
"I think it's just being able to execute in whatever situation that's there," Crosby said. "Whether you're creating chances or you're just creating zone time, I think that helps to get momentum."
In Game 1, Hornqvist played right wing alongside Crosby and Guentzel. In Game 4, Dominik Simon was elevated from second-line left wing to replace Hornqvist, who moved to second-line right wing.
