It would be a huge mistake if the Jazz overpay to keep Hill and Ingles and guarantees Diaw's contract.
You don't want championships with this type of mentality.
Why?
Unless you can get something better you keep the talent you have. They can all be trade chips in the future to build something better. You dont let good talent just walk away for nothing that does not bring championships. We need players like Hill and Inlges to be good enough to attract talent and to have trade chips if we have someone we can get. I cant think of other championship teams that let good solid talent walk away for nothing. For example San Antonio traded Hill for the right piece at the right time. They didnt just let him leave.
