@Cavatt had asked elsewhere what development, if any, is there left with Prince and specifically about his shooting. Here is what I found about his offensive profile in general:
Spot Up:

17-18: 2.0% frequency, 1.40 PPP, 69.6% FG%, 81st percentile.
So right off the bat, from a "what do we want him doing on offense" standpoint. Take the ball out of his hands, full stop. If there is any area the Cavs can and should develop, it's putting him in position where ~75% of his touches are coming in spot up, off-screen, or cutting situations where he doesn't have the ball. He clearly has the skills to be a good off-ball player, but he also clearly has shown over multiple seasons that he is a huge negative with the ball in his hands. He's atrocious driving to the basket, averaging 4 drives per game, a FG% under 40%, and a turnover percentage over 10% his last 2 seasons. But he's proven he can be a good catch-and-shoot player with multiple seasons with an eFG% over 60% in that situation.
With, when healthy, Garland, Sexton, Cedi, Nance, and Dotson doing most of the ball-handling/playmaking and a clear emphasis on wanting to play through our bigs in the post and on the elbow, we should be in a position to do just that with Prince.
We need a catch-and-shoot presence as is. We are dead last in catch-and-shoot attempts per game in the league, something that I think changes when Drummond is moved (we average the 2nd most post-ups per game in the league, sure that takes away). As we move away from the post-centric offense and into more of a typical modern day NBA offense (pick and rolls, off-ball screens to get shooters open, drive and kicks) I hope we keep some of the things that came with it, specifically our wings consistency in back-door cuts this year (we are 3rd in the league in cut frequency as as a team). That kind of playstyle is right up Prince's alley in what he actually does well offensively.
I'll get to defense here a little later.
