Been a theory that Tanking existed in the past, but has not been such an issue with the draft allowances for Gold Coast last year and this year GWS.
Always thought while draft pick allowances were good they were subjective to teams tanking in the last weeks of the comp, but thought the solution was relatively simple.
A draft: The bottom 4 teams (13 14 15 16) raffle for the 1st and 2nd picks. (those teams that win a pick are excluded from Draft B)
B Draft Then the bottom 6 teams (11 12 13 14 15 16) raffle for picks 3 4 and 5
The bottom 6 team not winning a raffle pick from Draft A and B gets pick 6. (if that team should happen to be bottom team you could consider them getting pick 7 also -priority pick) otherwise
Pick 7 goes to 7th from the bottom (of ladder)
Pick 8 goes to 8th from the bottom ...and so on (as per first round picks)
