So eliminate the picks in the same round and you get:
Portland trades: 10th (23), 14th (23)
Oklahoma City trades: 1st (26)
Explain to me the logic on this very suspect "veto" system...
Clever... but eliminating those picks in the same round defeats the purpose of the whole trade.
I don't see how you argue (in your case) moving up 6 spots from the 4th round, #2 to the third round, #26 (six slots) was worth several additional picks, but that moving up 15+ slots in the 3rd, 5th, 7th, 9th, 11th, 13th, and 15th was worth nothing. That's a total of 105 draft positions switching places, plus two late round picks. I'm not sure if it's worth a late-round #1 (beauty is in the eye of the beholder), but it's worth a lot more than you're giving it credit for.
