Though the 2010 Stanley Cup championship still resonates for Blackhawks fans, it’s old news to the Blackhawks. But it’s an undeniable point-of-reference with the Hawks on the brink of being on the brink against the Red Wings.

With the core of stars from that Cup-winning team intact, the question looms now more than ever, with the Blackhawks trailing 2-1 in their Western Conference semifinal series heading into Thursday night’s game at Joe Louis Arena: Does this team have that intangible that propelled the Hawks to play their best when they needed to most in 2010?

‘‘Each round you play, there’s probably a defining moment that got you over the hump or turned it in your favor, whether you captured the momentum or sealed the momentum,’’ coach Joel Quenneville said.

The Hawks were in a similar bind as they are today when Quenneville’s defining moment ocurred in 2010. With their opening-round series against the Nashville Predators tied 2-2, the Hawks were seconds away from losing at the United Center and facing an elimination game in Nashville, when Patrick Kane scored a short-handed goal to tie the game with 14 seconds left in the third period. They won in overtime, when Marian Hossa came out of the penalty box after serving a five-minute major to score the winning goal.

‘‘To me, it was a defining moment for that round and all of the sudden, it seemed like we took off at that point,’’ Quenneville said. ‘‘That momentum and excitement, you can gain a lot as a team and whether it’s confidence — you feel it.

‘‘And the guys rally around a certain thing, but you progress as you go along and that momentum and excitement can be huge. When you look at the past and why you won or didn’t win, it’s always a defining moment that got you going in the right direction.’’
