As I tried to make clear, I was looking at line up numbers from last year to assess what types of players worked best together with Tatum, Brown, and White. I looked a Queta as the primary big but also looked at Vucevic, two very different types of bigs. It would be nice to add (2) starters to the team so that Pritchard, Hauser, and Queta can go to the bench (or maybe Hauser is traded to make room for a different player), but I am not so sure how likely that is.
The starters will likely be constructed as follows:
Guard + White + Brown + Tatum + Big
The guard could be Pritchard, Hauser, Walsh, Hugo, Schierman, or someone new.
The big could be Queta, Vucevic, or someone new.
I agree that ideally, the guard would be someone who can handle the ball and score, while playing respectable defense. Same for the big, ideally a scoring big with some defense. None of the current options are really starters, that is the problem. All of them are better suited as bench players.
So what is the priority if you can only realistically bring in one starter level player, either a guard or a big?
