We might really have to create a own thread for the Swiss Coaching situation. I really don't want to insist in here. It's going way too off-topic.
But that my comment about Wohlwend was critisized from opposite sides says it all, how much he polarizes.
And just to answer the questions about Krueger.
IMO Krueger is a smart communicator and a fantastic teambuilder, but a way overrated coach longterm. As crucial he was in the first half of his career in Switzerland, implementing defensive commitment, teamspirit and self-believe, as much of a hindrance he was in his second half. He couldn't handle critic, even if he went on in the media with his more and more irritating mantra-like positiv thinking and teamspirit blabla. With every failure he got more anxious, he had no concept of risk or offensive tactical versability, no courage, no poitivity, no idea how to properly use the growing talent pool, he basically didn't believe in his own words. So he let them underplay their talent for shorttime success only, and he had with Kölliker a guy who did the same with the juniors as well, pure result hockey as well, no intent of letting them take risks and acctually have a chance to develop. They waited way too long to replace him IMO.
I wasn't surprised, he wasn't more than 1 season in headcoach duties afterwards.
