Trotz would not disclose who his starting goalie would be Friday, saying he didn't want the Hurricanes to know until game time.
The Islanders trail the best-of-7 series 3-0 and are in danger of being swept in the Stanley Cup Playoffs in a best-of-7 for the second time in their history; they were eliminated by the New York Rangers in four straight in the 1994 Eastern Conference Quarterfinals.
"We haven't gotten the results we wanted, so yeah, absolutely 100 percent," Trotz said after practice Thursday.

Goalie Robin Lehner, a finalist for the Vezina Trophy as the top goalie in the NHL, made saves on 33 of 36 shots in Game 3. He has allowed six goals in three games against the Hurricanes and has never defeated Carolina in seven career starts, including this series.
Thomas Greiss, who went 23-14-2 with a 2.28 goals-against average, .927 save percentage and five shutouts in 43 games, won three of four starts against the Hurricanes in the regular season.
Lehner accepted the blame after Game 3 when his attempted pass behind his net to forward Josh Bailey was intercepted by Hurricanes center Sebastian Aho and resulted in the game-winning goal by forward Justin Williams at 10:15 of the third period.
Trotz was asked if any possible changes for Game 4 could include his starting goalie.
"I said all positions," Trotz said. "That's a position. All positions. Quite frankly, I haven't told them who's playing in goal and I haven't told them their lines."
