This is one of the most interesting rookie situations in the league because Utah already has young players who believe they are part of the future.
Keyonte George is not some placeholder point guard waiting for the No. 2 pick to take his job. He established himself as a legitimate scorer and Utah committed to him long term. Lauri Markkanen is still a proven scoring forward. Jaren Jackson Jr. gives the Jazz a veteran defensive anchor and frontcourt scorer. Ace Bailey showed real progress during the second half of his rookie season. And Isaiah Collier has already shown a natural ability to create shots for teammates.
That means Peterson's first challenge is not "save Utah." It is fit into something promising without shrinking his own ceiling.
The Keyonte-Darryn backcourt is where this gets real. Both can create. Both can score. Both are young enough that Utah should not force a final hierarchy in October. The best version is not one guard standing around while the other plays. Peterson has to prove he can punish closeouts, score off movement and make quick decisions without needing every possession to start in his hands. Keyonte has to show he can toggle between lead creator and scorer.
Lauri helps because he does not require a ball-stopping role to create offense. He can screen, pop, cut, attack a mismatch and punish a defense that tilts toward the guards. JJJ can give them a defensive backbone that last year's Jazz desperately needed.
Then there is Ace. We already viewed Bailey as one of Utah's highest-upside pieces, and his late-rookie growth makes the roster puzzle even more interesting. If Utah uses Ace as an aggressive second-unit scorer and still closes with him when the matchup works, the Jazz can develop all of these young players without forcing everyone to hunt the same shots.
Collier matters too. A guard whose first instinct is to organize can keep lineups functional when Keyonte or Peterson sits. That allows Peterson to spend some minutes simply being a scorer rather than always being responsible for the entire offense.
Our Donovan Mitchell question is about role, not a prediction that Darryn becomes Donovan. Mitchell eventually became the Jazz perimeter star who could create a quality shot when structure failed. Peterson has that kind of self-creation upside. If we reach March and Utah is putting the ball in Darryn's hands for big possessions while still getting growth from Keyonte and Ace, the entire rebuild starts to look different.
Earlier in our 4DK offseason work, Peterson was our ROY lean. We have not cooled on the player. The difference now is that Utah's full roster makes his rookie year less about volume and more about learning how to become a star inside a real ecosystem.
