Let's face it. None of us really know how team-mates gel or don't. And those who are involved in the club and may know, shouldn't be spouting their knowledge on any rifts anyhow.
However, I have my personal theory (yes, hypocrisy, but as a BF member I am damn well entitled to it!)
Before the trade period someone suggested that one of the big 5 (not Jack) would be traded to break up a (clique / clicky ?) group.
Couldn't see it possibly being Martin after his season, couldn't see it being Cotchin, Rance may be a strange cat but that didn't fit either.
Deledio seemed to be the obvious one.
All the many discussions re Captaincy on this forum - Jack & Rance have their faults but already are "Generals" of their end of the ground anyway. Martin still young, too shy, etc and noone else can really be considered automatic best 22.
So it comes down to Cotchin or Deledio, with many posters believing it should have been Deledio. What if Deledio believes this himself? One of the biggest problems the club has is onfield leadership. I think Maric provided good support to Cotchin but with his absence from the team there has been SFA onfield support for him.
I'm not trying to hang shit on Deledio, but I think it's possible he was head of a group of senior players that may have somehow undermined Cotchins leadership rather than fully supporting him. Just like BF posters, maybe there were a certain number of teammates who felt he would be the better captain. You can still be a good bloke, a great bloke and still be affected by stuff like that and find it hard to give 100% to someone who's in a position you feel should be yours.
Anyway, just a personal theory. Feel free to disagree or crucify me. If its partially true it may mean better team harmony and onfield leadership for 2017.
