Felix Koslowski is now officially the head coach of German NT. In 2016 he didn't have a "real" contract, now he does. However the press release does not say anything about the duration of the contract, just that 2017 is an important year for NT, that they want to qualify for WCH and reach quarterfinals in ECH...
I think it's a good choice. I was sceptical last year, but Felix did a very good job in summer with the reduced team and the players like him a lot and speak very positive about him as coach.
