Well put, this is pretty much exactly how I view the situation.
It's an insult to even suggest Walters is the difference between last year and this year, the problems we've faced a far greater than one member of the coaching staff no longer being there.
Injuries, origin period, players playing out of position, losing and the loss of confidence that comes with that, other teams working out our game plan. There's plenty of reasons why, not that it really matters now, all that does matter is the team turns it around and proves to itself, and the rest of the competition that they are worthy competitors.
