In my opinion, Horf should essentially be told that he should consider himself an assistant GM, and name his price, knowing that whatever that price is, he, like Budcox and his teammates, will either be helped in the pursuit of a championship or, alternatively, he can make that exceedingly more problematic if he chooses to take all of the money and years on the table in a "maxed-max" contract. Just sign him as quickly as possible to gain certainty on that front, so that you can proceed with the rest of the FA decisions.
