With 2010 Stanley Cup champion stars Patrick Kane and Jonathan Toews leading the charge, the Blackhawks are the heavy favorites to win their second championship in four years.
"These guys are just hitting their prime," Clarke said. "For the next five or six years, they're going to be tough to beat."
Forget five or six years from now. Ask any team this season.
Corey Crawford (three shutouts) and Ray Emery have emerged into the NHL's best goalie tandem and Kane's 12 goals and 27 points are among the best in the NHL.
"Somebody jumps up and contributes a little more," each game, coach Joel Quenneville said. "Nobody wants to let each down and keeps pushing each other in the right way."
Like Chicago, the Flyers used two goaltenders, leaning on Pete Peeters and Phil Myre over the streak. The Flyers went 25-0-10 to set the record.
Amid the hype, the Flyers can serve as a warning sign for the Blackhawks. Not even the greatest of streaks can forecast a Stanley Cup championship. The Flyers finished 48-12-20 with 116 points but lost the Stanley Cup finals in six games to the New York Islanders.
"It's not, just because you have this streak, you're going to the finals," Propp said. "It's a grind to get there. I don't think you can take away from what we did during the regular season. It's just a whole new ball game once the postseason starts."
No team in any of the four major pro leagues has approached a streak like Philadelphia's. The NBA's Miami Heat have won 15 straight games — and many debaters would argue that streak is more impressive because there are no ties or points awarded for a loss.
Maybe, but that's an argument for another day.
Should the Blackhawks top the Flyers, they won't care what teams in other leagues do.
And the Flyers won't stress over losing their record.
"Whatever Chicago does, it didn't take away from what Philadelphia did," Clarke said. "The players that were part of the Flyers in those days can still enjoy what we did and celebrate what we did."
