I don't think the draft changed a thing about trading Davis. Except maybe make it easier for NO to trade Davis, since they now have Zion.
The rest of the draft is not strong enough to have impact, and NO will now look more towards obtaining young protected talent that are established. Players like Tatum, Brown et al that the Celtics are stocked with. The Lakers, too, though the Celtics have better players.
I don't think Ainge is in a position to draw any lines. Not with his problems running an underachieving team. He knows he has to get Davis, and he just hopes he has enough to get him. And he is a good enough drafter to get two or three players who can more or less fill holes left after any trade. That assumes the big money vets are still around, since he will have cleared enough salary in a deal to accomodate Davis.
