So what should we do? Change the coach again?
I'd say there has to be questions over the development process generally as so many good, young players go there but don't kick on to the next level until leaving.
The main issue as an outsider looks to be that this is such a young team, the leaders are young and this is too much for them to do alone. The oldest on-ice players are Zucker, Lafferty and Clifton. No disrespect to those guys but they aren't going to show the younger guys how to be leaders in a locker room and how to set a standard. The guys with As and the C right now all have the potential to be leaders long term but they need someone to show them how.
Move some assets and bring in say 3 experienced veteran leaders and it would help.
These guys might not be available but as examples of the types of players, Gudas, Kreider, Stamkos, Marchessault, Nelson, Palmieri, all would help this young side step forward.
The team has good assets that they can give up without affecting the core parts, so teams will listen.
