Reasoning:

Lakers - Nesmith fits the lakers needs for winning now and future as he’s 25. He brings good defense and great shooting which is perfect for the Luka system.

76ers - The 76ers don’t have a proper power forward and Walker could be their main PF for now and going forward. ( Not too sure what his value is)

Pacers - Getting rid of nesmith doesn’t make much sense, however this package improves their depth and the fits are good. Rui can be the starting SF or come of the bench and provide 12-14 points on high efficiency, he would fit the system well. Dalton also would fit nice and since hali is out and pacers don’t really have a chance at competing. getting dalton and letting him develop for a year could pay of well and he could be a good piece for the pacers future.

Plus decent draft
