Staal scored the game-winning goal 1:12 into the ensuing power play to give the Wild a 2-1 lead.
It was a stretch of two minutes in a 60-minute contest. But it was a defining two minutes started by Dumba's physical play.
"Everybody can see that, how the atmosphere and the emotions come up," said Wild forward Mikael Granlund. "Those are big plays and they get the whole crowd into it. It was great to see those kind of hits."
Minnesota is a better team when the crowd is engaged in the game. That's the opinion of head coach Bruce Boudreau, who stood behind the Wild bench at Xcel Energy Center for the 93rd time on Saturday night.
"When the life in the building gets going then we get going," Boudreau said. "We are usually pretty quiet in the first period and we played pretty quiet in the first period. I've been here three years and when the energy is in the building and it's loud, it affects the players big time. We want to keep that up."
Dumba's physical nature has started to trickle back into his game this season. When he was drafted seventh overall by the Wild in the 2012 NHL Draft, his highlight film was chock full of hits similar to the one he had on Saturday night.
Those hits have been few and far between in the NHL. With the exception of a big one on Patrick Kane a few years back, Dumba has picked his spots much more carefully.
This season has been different. His play Saturday was perhaps his third or fourth highlight-reel hit in Minnesota's first 10 games.
"When I was younger and in juniors, I hit a lot," Dumba said. "Now, it's starting to come back a little in my game. The first couple years, you don't want to take those risks playing against men and stronger guys. I think I've just started to maybe grow into my man strength a little, and that's helped."
A 50-point defenseman for the first time last season, the Wild believes he could be just scratching the surface of his offensive ability from the blueline.
Doubling down on his physicality has the potential to give opponents one more thing to ponder when approaching the Wild goal.
"When he plays with a little bit of an edge and on that line, I think he becomes a better player and definitely creates some energy in the building and I thought we got a little - we were engaged all night - but it adds a little bit more animosity," Staal said. "I think this game's gotten so fast. Sometimes if you don't have that quickness you can get caught out of position and then caught in the wrong time to finish your check. Dumbs is smart, and he knows when to finish and when to make the right read. It was a good hit there."
