Pretty much everyone wants the Lakers to make a bigger deal. It feels unlikely. The star-trade market is nonexistent, and L.A.'s top-shelf offer (salary, two firsts, and two swaps) can be easily beaten unless someone (like Bradley Beal) is dead set on getting their way to Hollywood.
Adding an actual wing goes a long way. Richardson would immediately close games while giving the Lakers a more viable option against the other team's best perimeter player than LeBron James or Rui Hachimura.
Beverley instantly becomes a buyout candidate in San Antonio. The Spurs should be fine parting with Richardson, a free agent this summer if it secures them two could-be-interesting second-rounders.
