Well, I think the beauty of this year (if there is any beauty at all) is that we don't need to do anything.
For the past few years, there's always been pressure to upgrade because we had to maximize the potential of the team in a very narrow (and rapidly closing) window of contention.
This year, there are no expectations. If the team clicks and exceeds expectations, great. If not, they get a shot at several great players in a loaded draft.
So Danny should just ride things out. If someone offers him something worthwhile for one of the vets, he should do it. But there should be no rush to trade anyone unless a valuable building block is offered in return.
