But how to make sure that Lakers stay relevant but mostly build for the future?

The Knicks move off of some lesser depth and Mitch to add the wing and center depth they Desperately need. The clippers move off a bench player who is less needed with Kawai back to add a starting PF. The warriors pair Lebron with Curry and see if the Olympians have one more run in them. The lakers get Mitch, Kuminga and Wiggins to start with Reeves and Doncic. This bench would also be extremely deep and Knect has time to grow now.
