Lakers use all draft assets + Knecht to grab Johnson and a late first rounder to draft to grab a center to run with Luka: (Maxime Raynaud, Ryan Kalkbrenner, or Hansen Yang). Gives them another true 3 & D defender and a young (albeit inexperienced) center to run with.
Nets grab future assets from the Lakers for one of their worst 1st round picks and pick up Knecht. Vanderbilt is a good defensive player and if he can show that he can shoot more this year might be able to flip him to a contender at the deadline.
All things considered- I'm guessing the Nets are likely able to find a better package for Johnson.
