I dont think the points system is the main criteria. Most clubs seem to favour a top 5 or top 10 (changing each year depending on the draftee list)Points wise 3 for 15 and 17 favours us by about 100 (2234 v 2137)
However if you look at wjere the actual pick would fall 5 for 17 and 19 it then favours GC (1878 v 1973)
Being equal on points helps them with the haggle, getting the final deal. Eg throw in a 3rd as well- nah on points we only need to give a 4th.
But the main part of the deal has to be win win.
A top 3 for 2x late first round? Not equal.
Unless GC have a specific need (rucks) that will be around then.
Even clubs desperate for a lot of quality, such as crows and North were in the last couple of years haven't wanted to downsell their top 5 pick.
I can't see the suns being interested.
Crows yes
