Should the games go to par, that is should the teams ahead beat all the teams they come up against below them, the final table should look something like this (mind you it never goes as expected so this is just for fun)
Storm 44
Bronks 38
Roosters 36
Sharks 36
Sea Eagles 36
Eels 36
Cowboys 34
Panthers 30
Dragons missing out at 28.
If the table finished in such fashion, for and against will have a major say in 3rd and 4th. The Sea Eagles have the third weakest for and against of the four finishing on 36 but the difference is not great and Manly have the easiest final four matches. Possibly could go down to the wire as they say.
