Why does everybody assume Luka will stay in LA?

Getting Luka is obviously fantastic news if they manage to extend him. But players of this caliber don't move in free agency because their current team is the only one that can offer them a super max, which means moving teams effectively costs the player 100m.

LA will not be able to offer doncic a super max, which means he will be likely to sign with the best team available to him. There should be at least 10 teams willing to sign him, and all of them will be able to offer his the regular max. It's only logical that he should go with the best team of the bunch.

What am I missing?
