This is where things stand in my mind:
Holiday Pritchard Springer
White Hauser Scheierman
Brown [ Vet? ] Walsh
Tatum Horford [ ? ]
Porzingis Kornet Queta
2-way: [Watson?], [Davison?], [ ? ]
We have 13 signed and no one officially yet on 2-way deals. As it stands, Kornet will start the season as the 2nd team 5/C and Horford the 2nd team 4/PF. Horford will probably start though. What the priority should be changes if you consider Porzingis in or out. The roster with Porzingis injured cries out for a 2nd team PF but as soon as Porzingis is back, that player becomes the 3rd team PF and probably hardly plays (certainly hardly plays in the playoffs), unless they are better than Kornet.
If you look at the roster with Porzingis playing, which you hope is the case for most of the season and the playoffs, then the biggest hole to me is a 2nd team wing/swing forward type.
The problem for me is if you target a big, it has to be someone that would be better than Kornet or Queta or what is the point. We may not be able to even get Tillman with a min contract (all we can offer). Drummond got $10M (about $5M per season). Are Saric or Theis gettable for min contracts? Maybe. But are they any better than Kornet? So they come in and eat some minutes for a couple of months and then sit on the bench the rest of the season/playoffs? Is that really worth it for what it would cost in tax penalties?
I understand that we can do both, get the wing/swing and the PF/Big and that is what the Celtics should try to do. I just have my doubts that the big we get with a min contract is going to do much.
