If anything was indicative in this game, it's that the Flyers certainly know that a lot of change could lie in store, but the results aren't going to change without max effort.
The Flyers had 37 shots to 27 for the Avalanche, and came close to ending the game on numerous chances. Ultimately, the game took a shootout to decide, but it was a classic case of near misses and little bounces going the wrong way that did the Flyers in. Here is the Postgame Review.
