These 1 year of Mookie vs X, Y, Z trade discussions are not particularly useful IMO.
I think everyone understands if we were never signing Mookie long term, then of course 1 season of Mookie could only be worth so much and a trade made sense.
We'll probably never know Mookie's mindset for sure and the chances of resigning him. But I think if the FO was aggressive up front there is a good chance he would have stayed, and then the calculus completely changes.
The FO wasn't convinced he would be elite this long, they treated negotiations as such, and it backfired. I hope Wong keeps his hot streak going, but not keeping Mookie was still a huge disaster given how great he has been since.
