Best case scenario is we win and the Dogs win so Storm finish 6th and we don't have to worry about them until Prelim at the earliest...
At the same time a loss and finishing 6th is not the worst thing, an easy 1st up match v Rabbitohs then a trip to Townsville against perennial chokers the Cowboys followed by a Sydney game v Roosters or Dogs
Worst case is probably as it stands, finish 5th, smash Dragons then face Storm in Melbourne, survive and get Donkeys in Brisbane!
As for Prelim hosting, I'm worried now because the way the system is designed is winner of 1 v 4 and 2 v 3 gets home ground advantage, but seeing some other concern and the ladder predictor, who knows? I found the same thing doing the ladder predictor that Week 3 seemed wrong!
