Like, you Iam somewhat unsure of where the lines of responsibility ends; imo, Shaw is the hedge - just in case the team starts off slow or is struggling to make the playoffs and some changes are needed to change the fortune of the team - very similar to what the Habs did when the Habs replaced Julien with Ducharme and from there, the team took off.
After this offseason, there is alot more pressure & eyes, to see if the staff can deliver - to me the biggest X factors are: the coaching staff and if the players will buy in.
