The Sharks lost Games 1 and 2 in Pittsburgh by one goal each. They beat the Penguins by one goal in Game 3 at SAP Center but lost 3-1 in Game 4 on Monday in San Jose.
Game 4 marked the first time the Sharks outshot the Penguins in a game in the series (24-20), but they allowed the first goal for the fourth straight game and have yet to play at any point with the lead.
"We want to win one game and get a Game 6 back here at home," DeBoer said. "I think we would be comfortable in that spot that we could get it to go seven. But short-term, I think we've got to go in and win one road game. We've been the best road team in the League all year. It's not going to be easy. Yeah, I think our game has grown through the series. I think we cleaned some things up. We limited their shots last game from earlier in the series.
"I thought every game, we created a little bit more chances to score. I think our big guys have gotten more shots off and more looks as the series has gone on. We're doing some good stuff, but you can't change the fact that we've played behind the entire series, and that's something that we have to get fixed."
The Sharks had a League-best 28-10-3 road record during the regular season but are 5-6 in 11 games away from home during the Stanley Cup Playoffs.
