Queta has a club option for a regular roster spot. I guess in theory, he could go back to a 2-way deal, but that doesn't seem likely (and there may be rules against it). His option has to be decided by Jun 29 so we will know soon on him. If he could be signed to another 2-way (and would accept that), that would be great.
With Brissett out, and assuming Mykhailiuk out, we are at 11 spots when Hauser and Queta (team options) are included. Signing Kornet and/or Tillman would take us to 12 or 13. I think we are going to need a vet wing/swing type to replace what Brissett was supposed to be. I see it looking something like this:
Holiday Pritchard Springer
White Hauser-TO [ ? ]
Brown [ Vet? ] Walsh
Tatum [ Tillman? ] Queta-TO
Porzingis Horford [ Kornet? ]
Hauser and Queta are both team options so there is some question on them. Kornet and Tillman are both UFA so are not certain. Probably only 2 of Kornet, Tillman, and Queta come back. And keep in mind that that last 2 seasons we started with only 14.
