OK so I took a look at the GC rort of last year.
They entered the draft with a bunch of picks from other clubs, so they started the trade period with 5,453 points.
They did a number of trades, I won't go into the 1's that involved players as they all look like reasonably fair trades on both sides.
The pick trades a re a different scenario.
They traded with the Dogs and gained 762 points. They traded with Melbourne and gained 1057 points. They traded with North (actually lost a few points but moved a pick to 2024), they traded with brisbane and gained 427 points, and they traded with Freo and gained 124 points. The last 2 were trades at the draft.
All in all they gained from pick trading 2,297 points and moved 1,878 of those points into 2024 (Dogs 1st and Norths compo pick).
So their net points for 2023 were 5,872.
Their 4 bids, netted them a combined discount on those picks of 1,365 points, so collectively the gains from the double whammy of selling your high picks for a massive profit, and then profiting from the discounting was worth 3,662 points!! 20% more than the number 1 draft pick value!! Crazy good value they generated, basically a free Harley Reid and a bit more.
So I rolled my profile in there. I used the below premium measures.
1 - if a pick was within 10 picks of the bid - no discount or premium - pay market value
2 - If the pick was between 10 and 30 picks of the bid - 10% premium
3 - If the pick was above 30 picks from the bid - 20% premium
4 - 1st player - no premium. Additional 5% premium for each additional player, ie 5% for the 2nd, 10% for the 3rd etc
So Walter included a premium of 10%, Read included a premium of 15% (potentially could have been 25% - without doing the full draft again its a bit tricky to find out where their picks then fell), Rogers a premium of 30% and Graham a premium of 35%.
Essentially an increased cost on what they paid of 2,412 points. They would still have gained due to the pick trading down, and clubs seeing value in bidding for higher picks (and this is a good opportunity for the other 17 clubs), but its not the rort that it seemed to be.
For example, due to where their picks fell, they started with 5,453 points and needed to generate more than 7,865 points to get their 4 boys. They did that through pick trading, but they wouldn't have been able to trade those picks into 2024, they would have actually have needed to trade more into 2023 to pay for them.
Personally I think this system works, maybe the %'s etc might not be right, or we might prefer to play with pick values rather than premiums, but it seems the simplest way to fix the rort where you can generate that amount of value in trading down your picks, but also gaining the discount. Thats the biggest rort. Trading down and providing others access to high draft picks isn't a big issue for me, its the differential in trading value compounded by discounting that is the biggest issue for me.
