Well, Luke Walton will be fired, no question about it. Very likely getting rid of all vets on 1-year deals and probably trading 4 of the 5 young dudes they have. Other than that I don't see them land any notable free agent: Durant, Kawhi, Klay or Kyrie. I'm pretty sure Pels ain't trading Davis to Los Angeles either, no matter what offer they send, it's just not gonna happen.
Don't forget that Magic and Rob Pelinka have no prior experience as president and GM, some very questionable signings and trades over the last two seasons prove that; Zubac for Muscala straight up was a head-scratcher.
Anyway, some dude over Reddit broke down Lakers 2019 free agency, you might want to check it out.
