Providence rallied to win Game 6, but coach Kevin Dean warned against relying on another comeback. Four games in this series have been decided by one goal and three have gone to overtime.
"We just have to make sure that we don't have a letdown," Dean said. "We came back with some good resilience, and the guys really turned it up, but we can't afford to have that start [Wednesday]."
Providence outshot Hershey 110-43 in Games 3-5, although Hershey won two of those games in overtime.
"We don't have some of the pedigree in scoring that they do," Dean said. "[Our scoring] is going to be a little more through attrition, second chances, and that is how we got back into [Game 6]."
Providence has relied on a strong neutral-zone game to set up its heavy forecheck and wear down Hershey.
"I thought we had a good first three or four games in that regard," Dean said. "The past two games, I don't know if we have been as physical. It takes energy to be physical. ... But I think it should pay off. We've been talking about it."
Dating to the 2016 playoffs, Hershey is 3-1 when facing elimination. Hershey also staged a rally late during the regular season to earn a playoff berth in the highly competitive Atlantic Division.
Hershey is without No. 1 goaltender Pheonix Copley, who left Game 4 with a lower-body injury and has missed the past two games. Vitek Vanecek has a .919 save percentage since taking over.
"We've been very resilient throughout the year," Hershey coach Troy Mann said. "When we've needed a big performance, we've gotten it."
