Who do they edge out?
We have Sydney, Melbourne, Roos, Carlton (yeah.), and even Port who could finish in the middle order. I think roughly it'll end up being C'wood, Cats, Saints, Dogs, Hawks, Adelaide, Dockers who make up the top 7, so who gets the 8th spot out of those remaining 5-6? I think the only true 'locks' for bottom four are Richmond, GCFC, Brisbane and West Coast (will fade hard).
All my opinion though, however I think they will be very, VERY, close.
I don't like getting too much into these opinion pieces because time will tell. But there is not a snowflakes chance in hell that the top-4 as you have listed will be the same as last year. That would be the same top-4 three years running.
I made a thread a while back that showed that for 14 consecutive years (1995-2008) at least one team who missed the finals completely made the top FOUR the next season.
For fourteen years in a row.
Then in 2009, the streak ended and all the top-4 made the finals the year before.
And in 2010, not only did the top 4 all make the finals the year before but they all made the top-4 the year before!
Now, with the AFL's equalisation policies there has to be a breaking point. There is no way it will happen three years in a row. It just won't. It's against everything the AFL sets up their league to be.
Don't be surprised if there are a couple of really big sliders this year. I reckon at least one and maybe two top-4 teams from last year will slump to be 50-50 sides, which will put them on the fringe of, or just outside the eight.
