Correct. Payton gets credit for identifying players to get. Loomis gets credit for finding a way to get those players, like creative contracts and trading up in the draft.
You're not getting any of that from me. If you are, then you need to re-calibrate your detector, because it's giving you false readings.
One of the many things he does to run the team is to facilitate the head coach. It's pretty straight forward.
Oh, I see, you only give Loomis credit for allowing Payton to make mistakes. You don't give Loomis credit for any of the good things he let Payton do. You're doing the same thing you are "detecting" other are doing, only you fault Loomis for all of the mistakes made and don't give him credit for any of the success.
