Had a go at a home made ladder predictor and I have the final ladder as
1.Melbourne
2.Souths
3.Roosters
4.Dragons
5.Panthers
6.Warriors
7.Sharks
8.Broncos
Each teams run home in terms easiest to hardest(based on current ladder position) with best and worse possible finish in brackets)
Dragons(1st,9th) Eels,Tigers,Dogs,
Knights
Broncs(1st,9th) cows,souths,Roos,Manly
Warriors(1st,9th) knights,Dogs,Panthers, Raiders.
Storm(1st,8th)sharks,Eels,Titans,Panthers
Roosters(1st,8th) Souths,Raiders,Broncs, Eels.
Panthers(1st,9th)Titans,Knights,Warriors,
Storm
Sharks(1st,9th) Storm, Cows, Knights, Dogs
Rabbitohs(1st,8th) Roosters,Broncs, Raiders, Tigers
Tigers Raiders, Dragons, Manly, Souths
In terms of us to reach 6th had us losing to Panthers but winning other 3
To make 1st we need;
To win all of our games
Bunnies to lose 3 of next 4
Storm and Roosters to lose 2 of Next 4
Panthers and Dragons to lose a game
Broncos and Sharks can also win all of theirs but we need a better f/a.
To miss the 8 the Tigers need at least 2 more wins than us (or Sharks/Broncs) plus a couple of big scores.
So pretty much if Tigers lose 1 more we only need 1 more win and to keep our f/a intact.
Otherwise 2 wins should be enough
