I suspect what will happen is Ainge will deal Tatum et al for Davis, and Kyrie will extend in Boston.
I agree that that is likely Plan A (and B, C, D, E, F ....)
If that's what happens, I hope for the following:
Horford is still on the team.
Smart is still on the team.
They fill out the bench with good character, defined-skillset veterans.
Examples:
Trevor Ariza (MLE?)
Demarre Carroll
Taj Gibson
Robin Lopez
Wilson Chandler (MLE?)
Iman Shumpert
Jared Dudley
Ish Smith
Pat Beverley
Thabo Sefolosha
Justin Holiday
Ed Davis
Dante Cunningham
etc.
There won't be much to work with in terms of cap. Hopefully Danny will avoid taking on too much bad $$ from New Orleans.
My strong feeling is a team built around Kyrie and AD would need to have a lot of established veterans who will tune out the nonsense and will know and accept their role without worrying about what Kyrie or AD, or anybody associated with Kyrie or AD, is saying in the media.
I suspect both Jaylen and Jayson will be gone along with Robert Williams and most of the team's draft picks. That's fine, because young guys won't have much of a place on the team after an AD trade, anyway.
The question is which of Smart, Horford, and Hayward will go out the door in order to make $$ work. As of right now it seems like it'd have to be Smart, as much as that pains me. I can't see a team wanting to take on Hayward based on how he's played so far this year. I can't imagine Horford would want to opt in to the last year of his deal just to get traded to New Orleans.
