Brisbane currently have 14, 52, 67 for 1476 points.
Bid at pick 1 and they need 2400 points
Pick 2 = 2014 points
Pick 3 = 1787 points
Pick 4 = 1627 points
Pick 5 = 1502 points
Brisbane need to trade their pick 14 (worth l1161) for more points as 14 will get eaten up and they are short. They dont want to carry over to next years first round pick. Pick 14 will get more points in a trade for multiple later picks. Can trade future picks or even trade a player for points too.
They don't want Richmond bidding at 1 as that is 400 more points than North at 2 and they dont have.
Richmond has 2,000 points in picks from pick 33 and has built up the picks for this exact type of trade. So at this stage it is in Brisbane's best interest that Richmond don't bid at pick 1 but do a trade for points for pick 14.
Brisbane will take him no mater where he is bid at so the value for Richmond is leverage and Brisbane's pick 14.
