The only way I trade any of the Big Three is if we get someone who is actually a potential building block for the future.
Unfortunately, most of the suggestions people make are either
A) Unrealistic trades that other teams would scoff at.
B) Realistic trades that simply net us overpaid role players.
With A, the problem is obvious. With B, the problem is multifaceted.
First, if we're trading Ray or KG for role players, one of two things happens:
1) We trade them for role players who also expire this summer.
2) We trade them for role players that go beyond this year.
In the case of 1, why bother? We'll be at the same spot this summer. With 2, it means we'll have to be paying 10 or 23 million dollars per year to role players beyond this summer. And that's not a recipe for rebuilding success.
Second, even if we find some "nice" players who are borderline building blocks, we have to ask whether we can afford to take on "good" players before we get great players. Too often teams sink money into guys who will be the 3rd, 4th, 5th, and 6th best players on the team before they address the 1st and 2nd, putting them into perpetual mediocrity.
That's not what I want to see happen here.
For the right deal, let's make it. However, I'm not sure there's actually a deal out there that actually puts us in a better position than just hanging onto the Big Three.
