What changes for Lakers: They get a real center, fix their rotation problems that they have right now, and with Gafford next to Lebron, they are a real lob threat. They don't throw away Knecht 4, still have a tuff white shooting duo and actual ability to defend.
What changes for Mavs: They are getting off Gafford, who won't be sitting on the bench and will be traded soon, they solve their rotation problems by having a solid 2-guard starter in AR-15, they don't have to bench PJ and they don't loose their shooting
LA starting lineup: Doncic-Knecht-James-Hachimura-Gafford
Dallas starting lineup: Irving-Reaves-Thompson-Washington-Davis
