If we could predict who could shoot this draft thing would be a lot easier. I think his shot looks good and he's not exactly a hesitant shooter despite iffy percentages. I'm confident he won't be a Favors where he can't shoot, and his other perimeter skills are much better. But I think realistically you're looking at a shooter between Aaron Gordon - Millsap. I think he falls somewhere in that range.
I love Walker Kessler, but I also think we need to think about the degree to which we're confident about him at C in the playoffs. Do we think of Walker Kessler as a Rudy level player where we're going to max him out, play him 36+ minutes in the playoffs, and (should) build the team around him? Or is he more like a Poetl/Jarrett Allen level player where we pay him a lot (not the max), he plays 30 minutes, and in the playoffs it's matchup dependent. I think there will be times where we love having the dominant defensive big, but other times where we want a smaller and more versatile 4/5 look with Lauri.
Personally, I think Hendricks is better fit with Kessler in mind, but Jarace is a better fit with Lauri in mind. If you want a more 5 out look with Lauri at the 4/5, I think you need someone like Jarace to make it work and I'm uncertain Hendricks is physical enough for that pairing. It's not bad with Hendricks, it's just iffy. But The Jarace fit with Kessler+Lauri on the court is also iffy so again it depends on what your plans are with Kessler and how you view him going forward.
