Look, if everything goes to form, you have two guys who you can squint a project out as true star pitchers in Schultz and Grant Taylor, and there is a lot of time there for that to happen. Taylor is still in A ball, which means at the very least two years away, but it wouldn't be crazy to say 3. Schultz just got to AA, and is under huge innings limitations. He is probably two to three years from a real starters workload. And that is just to get them here.
The next tier of guys is more of the they should be rotation guys, maybe even good ones, but they need some things to break their way for that to happen. That is the camp of Iriarte (control), Thorpe (how does a sub-average fastball translate to MLB), Eder (waiting for stuff to come back post TJS, Palette (another waiting to show that projected lottery pick stuff post TJS), Ky Bush (can he keep up a good year after a horrible 23), Tanner MacDougal (raw as hell, waiting for a breakout, could push into the top tier if his stuff steps up), Keener (years away, off to a good start). It is fair to think at least a couple of them make it, and a couple of them don't.
The tier after are guys who project to be more of end of the rotation guys at this point like Nastrini and Cannon. Sure you have Sean Burke, he's another who is recovering and needs time.
The rest I put more as lottery tickets and waiting to see what happens, but nothing you can really count on as of yet.
