I still feel that the most likely outcome is that we end up with Grant. That would leave us a "top 10" of:
White Pritchard
Brown Brogdon
Tatum Hauser
Porzingis (Grant)
Horford RWill
That is a very solid top 10. You could quibble that Pritchard and Hauser are "weakish" for your 9th and 10th players but there could still be some changes/adds to potentially reinforce this top 10. In addition to the 9 guaranteed contract in the top 10, my understanding is that Brissett and Banton are also guaranteed, so total right now is 11 guaranteed contracts.
After the top 10, if I have it right, we are trending towards some combination of the following for the remaining 5:
Davison
Champagnie
Banton
Brissett
Walsh
Kornet
This is a pretty weak group, even considering it is slots 11-15. I predict that some of these will end up as 2-way players and that we still may see a FA add or two. Griffin was useful in the regular season and I could see him coming back. There are still a few wings out there also, such as Oubre, so we shall see how it goes. Brissett may be in the Pritchard-Hauser range, I don't know. Kornet is useful enough as a 3rd string big. I don't really expect any contribution from Davison, Banton, Walsh, or Champagnie. To me, these are all potential 2-way players (replaced with some vet FA, or if extra players come back in a trade), or Champagnie for example, could easily be cut if his roster spot is needed. I guess Banton is Guaranteed so he can't be 2-way.
I don't see much happening until Grant is settled but I do think we are still fishing for some select vet FAs. Pretty much all we can offer right now are min contracts so no one good is going to be in a hurry to settle for that. They will play out other options. If we offer some of the MLE, that I think would hard cap us and we would need to have renounced or S&T traded Grant first.
