My guess: they anticipated continued improvement and that improvement never came.
You give a third year player a big contract not only for what he has accomplished, but for what you expect him to become over the course of that contract. The trade tells me that Snead/McVay didn't think Goff was giving them what they anticipated getting from him.
IOW they projected a growth path, paid Goff accordingly, didn't see the growth, moved on.
