It's pretty hard for me to see how a Davis trade works. There's no way to trade for him without including Tatum (the player that the Pels are rumored to want) and Smart (for salary matching). There will be picks included as well of course.
Unfortunately, I don't see any way to do it unless Smart is in the deal. The numbers just don't work. Maybe a third team could be involved?
The core of the deal would be Tatum & Smart for Davis. I guess it makes sense to do it.
Boston hasn't had any problem retaining players once they're here. I doubt they're worried about him walking. There aren't any better situations in the NBA right now.
There are several ways to do it. The easiest is to trade signed draft picks (trade eligible 30 days after signing) and Yabu.
That’s not enough salary going out.
Davis will make $27.1 million next year. Because we can't take in more than 125% of the salary we send out, we would need to send at least $21.7M in salary to the Pellies.
Tatum is scheduled to make $7.8mm next year. The OP’s scenario is that Memphis’ pick does not convey; an estimate of rookie scale for picks 13, 18, and 23 is about $6mm, which gets us to $13.8. Add Yabu’s $3.1 and you’re just under $17 million, almost $5 million short. You probably don’t even get there if you add Williams and Semi, who together will make about $3.5 million.
These numbers are a little rough - among other things I have to estimate the rookie scale - but it’s pretty clear that Tatum plus Yabusele plus three picks is not enough salary.
It’s certainly easier to get there without Smart if the Mem pick conveys - but that’s clearly not the most likely event right now so I wouldn’t focus on that scenario alone.
If we did throw in Smart we would clearly have the best offer - hands down - but of course it would sting. He’s such a great complementary player - and would be even more valuable on a team that added Davis to the starting lineup. I would still probably do it, subject to changing my mind if this team finds its top gear and gets to the finals.
