Well there are 52 points available in a season assuming you win all games.
28 is the magic number to make the Finals, so they should receive a minimum 26 point penalty all but guaranteeing them a bottom 8 finish.
They may just be forced to play as spooners by default for the rest of the season, regardless of their points value. Like the storm did. Let's not forget that they are playing with an illegal squad, and they need to rectify it. However forcing desntmatta to shed players now is unfair on the teams that havnt played them yet. All teams should be given the opportunity to take on the illegal team and then from 2017 squeels need to shed players. (i respect this doesn't factor in player attitude if your playing for nothing)
Docking them 4 points means squat when the team is an illegal team in red hot form.
Im thinking they may cop 12 points, which is all their points this season, plus an additional penalty of 4 points totally 16 points.
