I think there's no reason to debate Hauser vs Svi. Joe wants shooters, it's his offensive philosophy, and Brad is giving it to him with Hauser, Svi, and even Porzingis. I expect to see all three of them bombing away all season.
Outside of KP, I worry that the new additions are all pretty unreliable. Brissett, Banton and Svi haven't shown a lot of consistency, particularly with their shooting.
I hear you about Brissett and Banton. I wouldn't be surprised if those two don't see the floor much, particularly Banton.
Svi, Hauser and Porzingis are established shooters though. Those three with Tatum, Brown, White, Horford, Brogdon and Pritchard give Joe a lot of shooters for his 3 point offense. Rob has been working on his 3 point shot this summer too, but I don't expect much on that front.
Is Svi an established shooter?
Last year he had a good shooting year, on low volume. In 2022 and 2021 he was poor. In 2020 he was good. In 2019, bad.
So, five seasons, and he's shot well in two of them. I think he's a question mark.
I think you have to grade these guys on a curve. Svi in my mind is established for what he is, a decent bench guy. Even with his unevenness season to season, he still is a career 36% 3PT shooter. That is pretty good for your 11th or 12th guy. He has 252 NBA games including 55 starts as the basis for establishing that he is a decent bench guy.
If you are comparing him to all NBA shooters, no, he has not established himself as an upper end shooter. But if you compare him to all bench players in the NBA, he would grade a lot better. And I don't think it is recency bias to look at last season and say that he shot 42.4% from 3 in 32 games and conclude that this is what he is capable of, if placed in the right situation.
He is going to be 3rd string on the Celtics, bottom third of the roster. Relative to that population, he is pretty good based on his history. And he has some ceiling to get better. What more can you expect out of this level of player? He isn't going to play much, probably, unless there are injuries (plural). But if it comes to that, I think he will hold his own in the rotation.
