They didn't "blow up" the roster. The only guys we lost were Carter, who has never been a factor in the postseason runs they've had, and Richards, who, as great as he is, was our third line Center. We still have Briere and Giroux and JVR, and everyone on that fantastic defense.
As for the goalie, maybe he was questionable because of the guys he had in front of him. Even without Carter and Richards, the Flyers can score, and they're stacked defensively from Pronger and Timonen all the way down. It's an ideal situation for a goalie. And if he's a flop, they'll send him down to the AHL to get him off the cap and sign someone else.
The way I see it, the team is still very much a contender for the cup.
