It's not ridiculous to loose against Düsseldorf in the shoot out. That's sports, it happens.
The DEG played really destructive and used their chances from counterattacks very well. And the Eisbären usually don't look too good against teams that concentrate more on destroying the game instead of playing themselves.
Claude said in a post-game interview that they were not ready. I listened to the game on our radio and would say that he's right.
