Bylsma spent two seasons as the Buffalo Sabres Head coach from 2015-2017. In addition he managed the Penguins starting in 2008-09 season where he led the Penguins to a championship over the Red Wings. As an NHL head coach his record is 320-190-55. Jeff Blashill and Dan Bylsma made a connection while coaching team USA in Denmark.
Personally, I trust this move by the front office because it is clear that Blashill and Bylsma created a relationship that was solid. Blashill definitely had a say in this hire and hopefully they can work together on the bench. Also the fact that Bylsma has postseason experience could help down the road.
