I'm annoyed at how our season has panned out, too, and at BA's "tactics" - but for a little perspective:
Matterson missed 4 weeks (it's irrelevant why, he just did)
Lane has missed most of the season
RCG has had 2 lengthy periods of missed game time
Sivo has been rubbed our for a bit
Greig copped a long-term injury
Hodgson has been out for a long time (whether that's good, or not, is irrelevant to this point)
Brown stupidly got himself suspended for a third of the season
That's a hell of a lot of disruption.
It's not an excuse, but I think most teams would struggle if they faced similar levels of disruption to their season.
