Please allow me to go full on crazy.
How about this? And I know the salaries don't match, but let's pretend that this is the core trade, and the add ons will be filled later.
To Indiana:
Gordon Hayward, Kemba Walker
To Boston:
Malcolm Brogdon, Domantas Sabonis
Who says no?
So the team would be:
G: Brogdon
G: Smart
F: Jaylen
F: Tatum
C: Sabonis
That doesn't fill me with confidence to be honest.
I believe both Brogdon and Sabonis have seen their stat lines boosted by playing in a so-so Indiana Pacers offense that allowed them to do as much as whatever they want to do whenever they want to do it. Both players would see a drop off in another environment.
I see a lot of guys who are good but not great at things (especially at creating out on the perimeter) who can be duplicative of each other leading to diminished returns.
So better individually than they are collectively.
-----------------
I prefer the balance offered by Kemba and Hayward. I believe it is superior. Kemba's quickness and ball-handling offering a different dimension to the offense. Hayward as a more proven 4th option than Brogdon whose offensive influence was far less in Milwaukee when in a more similar there to here than what he showed in Indiana vs here.
----------------
Sabonis did a lot better than I thought he would this season but I am still not fully on board with his game. A big man who can't shoot and struggles on defense is a bad combo. Very good team offense with methodical isolation based individual scoring and strong rebounding.
I wonder how much of his team offense & rebounding can be obtained by a cheaper center who wouldn't cost us so much in a trade. I am still not convinced by Sabonis as a leading player on a top team.
Ultimately, it is probably my lack of certainty / belief in Sabonis that stops me from liking this trade. Others who rate Sabonis higher would probably like this trade more than me.
