Mavs get the Point Guard who adds formidable perimeter defence. Also picking up a mid-late 1st round pick.

Celtics get off salary and Jrue's huge contract. Pennies on the dollar, however they're well into second apron and will need to offload. Porzingis will likely follow this off-season. They'll however pick up Caleb Martin a great two way wing, Omax and some draft capital.

Lakers get the Center to Match up beautifully with Luka Doncic in Daniel Gafford.

Nets are ready to take on salary and future assets, They take on Klebers expiring for Lakers salary relief. They get a great offensive young guard in Hardy, Also add Knecht and a future first.

(P.S I don't think trading for Jrue is a good idea for Mavericks however if it does happen, it should look like this.) Ability to get a point guard and with the 19th pick, Get some value in either a backup center or whoever falls out of the lottery.
