Nick Grossmann (who blows) got hurt in Game 4. The Flyers have Gustafsson (who is probably their third or fourth best D-man but ran over the dogs of both Berube and Homer or something) and Hal Gill as healthy scratches. They used Gill, who proceeded to be at least the partial cause of two of New York's Game 5 goals and also missed a wide open net.
The Flyers' defensive CapGeek is the saddest thing in the world. A ton of money locked into players who range from below average to atrocious. Seriously, like $12 million for MacDonald, Schenn and Grossmann, who would all be healthy scratches on good teams. LONG TERM locked up.
