Pick one gives you the ability to get the BEST player in that draft so it’s value is more than just a combined points value.
Points are only good if you are matching a bid for a F/S or academy players if you have access to any.
Us trading our pick 1 for 6 and 8 would mean we miss a shot at the top 5 players and end up having to take slops from the remainder and the actual target of your pick is most likely gone.
“Slops” might be a bit extreme.
