I think another possibility is this:
POR: Andre Iguodala
Why we do it - Bring in a vet/champ who brings intensity, decent shooting and great ball movement. (Wes is gone with this deal)
GSW: JJ Redick
Why they do it - Cuts salary majorly to make room for Draymond's deal while picking up a great 6th man.
TOR: David Lee, #30
Why they do it - Fills their need for size, get a pick and Lee is expiring if it doesn't work out.
LAC: Chris Kaman, Allen Crabbe
Why they do it - Size, size, size... And a young player that they don't have many of.
