Cadeau and Jackson will be here next season, harder call on RJ. Maybe you intended to say Ingram rather than Jackson, I would think Ingram may be the most intriguing to NBA scouts and a big wing, may need to keep his shooting % up, especially needs to get his free throw % up.
Thing with RJ is this was to be his last season, the plan did not include him using his covid year coming in to this season. His size is a NBA concern, most likely would be a NBA PG, he is scoring a lot even being under sized in college. If you can make shots the NBA will have interest and RJ does that. No doubt RK is really enjoying this season so far, is he enjoying it enough that he wants more? Fact, RJ loves being at UNC, do not be surprised at all if after he leaves that he would still settle in the area.
But if he did come back, could he show an even higher level, a major NBA concern is where is his ceiling, is he playing close to it, do they see more to develop? He simply does not fit their meterics, to small and he isn't going to get any taller. I think that keeps him as a second round selection, could sneak in late 1st round if he keep shooting so solid. I do think he leaves but would not say it is a done deal at this point. He is or is about to graduate, he recently got married, he is old for the NBA draft. He will get a NBA deal but after that first contract his future is most likely to be in Europe. Has he qualified for his jersey to be raised in the honored section yet, seems like he may have but if not that I would think is a major item for him.
