.What's Uwe Krupp doing on the bench?
Assistant Coach (Maybe they should have taken Kreis instead, Krupps Assistant Coach during the last WC, or Kreis instead of both, Krupp and Hoefner, the U20 Head-Coach for years), if this answers your question and they obviously didn't make the right decisions e.g. the goalkeeper. Grubauer got 10 goals, Treutle only one (116 min vs 66 min goalkeeping). http://stats.iihf.com/Hydra/236/IHM236000_85A_4_0.pdf
Additionally from the outside it seems like that the team did dream from something else in the first period against Switzerland and when SVK shot a goal after 8 seconds in the second period as far as I remember. This is probably one of the best German teams for many years when you take a look on the single players.
