Assuming the type of guy David Quinn is, he probably was not expecting such a slow start to the season. The New York Rangers got off to a slow start and have had different issues in each game that required attention. There is a major focus on getting better every single day within the locker room.
The team as a whole has a variety of different players that all had different attitudes and mindsets. It is the responsibility of the coaching staff to channel the different personalities into a collective focus. If a coach cannot get through to their players, they have a short shelf life.
