Ainge has no clue he is getting who he wants at 3.I would suspect Ainge wouldn't pull the trigger on draft swap unless he was absolutely certain that what he was getting back was going to get him what he wants.
The Lakers could go either Ball or Jackson.
If he wants Tatum at 3 I will be even more pissed than now. All he got is 1 pick to go 2 spots. It's 2-5 next year or it's the 2019 Kings pick which is a pure gamble.
