Trying to make a list, and recognizing that hope springs eternal, I think these fanbases would decline a trade:
1. The Spurs. They're all in on VW.
2. The Lakers, only because they can't admit the truth. But if they were rational, they'd pull the trigger.
3. The Bucks. They've got legit superstars, and the fans love Giannis.
4. The Nuggets. The MVP is a hell of a drug.
5. The Warriors. Fans truly love that core, and wouldn't trade them even for better value. Plus, ownership and the arena.
Anybody else?
