This blurb from SI sums it up well:
“Jeter can’t be faulted for the no-trade clause that Stanton used to blow up his plans; that was the parting gift of Jeffrey Loria, steadfast in his devotion to screwing the fans of south Florida. But no one forced Jeter to work out trades before even knowing if Stanton would approve them, and no one made him offload his franchise player despite Stanton’s refusals destroying Miami’s leverage. Conspiracy theories will follow Jeter trading his best player to his old team right after taking over, but it’s not that complicated. This is just an owner completely in over his head getting worked by someone far savvier.”
