#3 for Russell is fair, assuming he burned bridges in LA and they love Dunn enough to consider it a win-win.
The remaining, where we send 4 spare parts for Randle makes no sense. If it's going to be a Russell and Randle deal, it has to at least be more like:
Russell, Randle
for
#3, Rozier, Bradley
Lakers can take Ingram and Dunn, and roll out something like Dunn / Bradley / Ingram / Rozier at the guard spots.
Then we do something like move IT+future picks in a Butler trade and hand the keys to Russell with Smart off the bench?
Not that this makes a ton of sense, but at least it sorta works out to say we'd end up with:
Russell / Smart / Butler (guards)
Crowder / Butler / Jerebko (wings)
Randle / KO / Amir / Mickey (bigs)
Seems like a lot of work to turn IT into Russell, Bradley into Butler, and Sully into Randle...
