hypen,
I don't think its all down to one factor. Its been a long and fair to say unsuccessful season. I'll take that one step further, its been yet another unsuccessful season following others of a similar nature. Its a young playing group but thats a minor additional factor.
Long, difficult, unsuccessful seasons magnify the aches, pains and gripes that come with playing elite sports. Players react by responding more to the gripes than they would otherwise do if they were feeling upbeat and enthusiastic. Right now, theres little to fight for and less to enthuse over. They are playing out the end of a dead season right now.
You won't be seeing them at their best because their best isn't there to see.
Bring back hope, bring back realistic goals, bring back some fun and you'll see players that belong at the this level. Without change, they won't look much better than they do now and thats not all down to them
