Lugano fans have short memories when they bash Fischer. He had two strong seasons before losing control during his third, but he managed to completly rebuild the team and create a title contender in the process. Playing Klasen and Fazzini at center while some players were not available is nothing out of the ordinary, these things happen during a club season, this is not the NHL where teams have almost two rosters under contract. You can reduce his hockey to "skate skate skate" as much as you can reduce Shedden's to "throw the puck at the net and hope for the best".
This is the best possible team he could pick, the only players you could argue should have made it are Bodenmann and Bieber, not exactly guys who would be game changers. Walker is the perfect fourth line winger and belongs here, there will be players like him as long as we don't have three Niederreiter-Brunner winger pairs and can afford to put Moser and Ambühl on the fourth line.
Picking the same team for all international tournament like in Krueger's time is completly unrealistic, things have changed, the season is longer and the player depth is better. And beside, Krueger was constantly bashed for liking his Della Rossas and Paterlinis over guys like Burkalther or Nüssli who happend to have a hot streak in the NLA. Whatever you do, there will be complains.
There are many people to blame before even talking about the coaching staff.
