Lot of aggressive comps here. Lar is purposefully being silly, but may be closest. These are very optimistic, but in an attempt to be realistic re: ceiling...
Rozier - Kemba (offense)/Bledsoe (defense). Hybrid, probably halfway to each. Would be ecstatic to see him find the success they have had. He's the biggest wildcard of the group imo.
Hunter - Kevin Martin (offense)/ Tayshaun Prince (defense). Hybrid, and if he reaches Martin's offensive production alone, I'd be jacked. Doubt he'll be Prince defensively, but if he can utilize his length similarly, could be a plus defender.
Mickey - No clue, as he's undersized for position and has a mix of big (more) and small (less) traits. At this stage, an Ibaka comparison is wildly inappropriate, but no idea of what to make of him. His size (at his position) doesn't historically translate to the NBA, but relatively speaking, not being fat and lazy may help his cause in the near future.
