Yeah I think defensively we are fine, but offensively our connection isn't there. Set shots have been a clear problem all year, but even so remarkably we are only ranked 12th for scoring conversion (goals / behinds) but it doesn't take into account OOTF's.
Our issue is we are ranked dead last for scores per inside 50's, like you say we are getting it in there fairly well, though we aren't getting as many repeat 50's as we used to get, but when we do there is little if any structure, no forward pressure to lock it inside 50 and we are therefore too easy to play against. We rank at 38% for scores per inside 50. The AFL average this year is 44% so we are a mile off at the moment. The good thing on the back of this though is when we do get shots inside 50, we are getting them in good areas, but unfortunately our kicking has not been good. With where we are getting shots, we should be top 6 for scoring conversion but as I say we are ranked 12th, and we can run off a list of easy gettable goals we should have had in pretty much every game this year (even the Crows game).
Defensively we rack up pretty well, 6th for scores per insider 50, but we generally don't give easy shots away, we rank 3rd in the AFL for defensive conversion %, so its pretty evident that our defence is keeping us in games (and we'd be ranked even higher if we weren't giving easy D50 turnover goals away every game).
Connection inside 50 is all about gameplan and personnel and I think we are lacking in both at the moment. We'll get the latter back at some point this year, but the former, I don't know.
