At that point in time, he still had significant value. We don't know if Sacramento ever had a choice between Simmons and Sabonis. It's quite possible that the Sabonis deal first came up after the Simmons talks cooled. I should correct that to say, I don't know.
The Atlanta freeze definitely raised questions, but I think there was still genuine interest in moving a unicorn to friendlier confines, especially somewhere that might be interested in building around him, like he wanted. Even after the disastrous tour in Brooklyn thus far, there has got to be some hope in the Net’s FO that he will heal and return at least to prior form. So, yeah, I could see the Kings looking at Ben a year and a half ago with great interest, before the herniated disc. However it went down, things have worked out well for them as well as Indiana.
