I'm not sure I want to ask this, but what are you trying to say here? Are you saying you're talking to people who directly know a bit about the Jazz's thinking? Or are you simply referring to the speculation of certain people with some interest in the Jazz?
Can you connect the dots a little more here? What does the Miami situation have to do with the Knicks? Where is the idea that the Knicks are treating the Jazz like they have to trade him coming from? It certainly doesn't seem to be what the Knicks are operating like in public (post-playoffs at least). If the Jazz weren't interested in the Knicks offer, why would they even engage with the Knicks?
I guess some of this could make some sense if the argument is that the Jazz didn't intend to trade Gobert and were originally interested in trading DM for the Herro package and retooling that way. But then the Gobert offer turned into an offer that couldn't be refused. Then the Herro package got put on hold because the Heat were actually more interested in Durant and were (and continue to treat) Mitchell as the fallback option. Is this basically what you're saying?
But even if this is the case, things still get murky. Why are the Knicks involved at all? Are the Jazz still operating on the idea that they want to trade DM no matter what? Otherwise, why would there be frustration with the Knicks negotiations? If the Knicks don't offer a sufficient package, just move on. Why all the leaks about being close to a deal?
