I agree that Lauri would prefer to stay & that it is definitely going to take an overpay for another team to acquire him but it seems pretty clear that our FO is actively looking to generate an acceptable offer for him. Otherwise why would they allow these rumors to persist, potentially upsetting the star that they're planning to build around?
I'm sure they would be comfortable with just extending & retaining Lauri for the time being if they don't receive the level of offer that they're seeking, but it seems pretty obvious imo that the FO wants to trade him for a haul. And I believe the rumor of not wanting to move him is just further posturing, similar to how it was rumored that we intended to build around Mitchell right after Gobert was traded.
Looking back, Ainge clearly had a plan all along. And trading Lauri was always part of it imo. Step 1 was to acquire draft picks, young talent (Kessler, Agbaji, THT, etc.) & flippable assets with the potential to increase in value (Lauri, Sexton, Collins, etc.). Step 2 is to cash in on those flippable assets & allow our young talent to develop, simultaneously positioning us near the top of two potentially historic draft classes.
Lauri's unexpected development may have caused the FO to genuinely consider pivoting & adding a 2nd star this off-season, although I believe those rumors to have been more posturing/raising prices for when it came time to deal him, but these persistent GSW rumors definitely seem to indicate that they are back to (or never left) wanting to trade Lauri. Just has to be at their price. I also believe GSW are being used for posturing, similar to NYK with Mitchell.
I'm sure we'd be okay with hanging onto Lauri, but plan A is clearly to trade him for a haul imo. As it always has been.
