Those teams on 12 can still make it. If sharks lose all their games and those teams win them all they will end up in front of the sharks.
If the sharks only win one game and a team on 12 win all theirs they will all be on 20 points. Then for and against comes into it.
FFS Looks like Manly most likely to win all their games.
8th place Sharks 18pts
Warriors 14 pts
Dragons 12 pts
Manly 12 pts
Tigers 12 pts
