Personally, I think positions 6-8 are all up in the air. I thought the Warriors were just about specials for 6th, but looking at their draw; it's not the easiest run home.
The Knights have a reasonable run, with four home games out of the last six rounds.
Prior to Friday night I would have said the 'Dogs were no chance, but they've actually got a pretty good run home.
I think the Tigers should get there and it will probably be between the Knights and 'Dogs for the remaining spot. As to the exact finishing order - who knows.
So in summary, I think positions 6-8 will be made up of three of the Warriors, Tigers, Bulldogs and Knights.
