I think like many fans, I had sky high expectations for Tatum this season. It was hard not to, coming off of his playoff performance. I agree with what many have said, that he took way too many low percentage, heavily contested mid-range shots, and when he did drive to the basket, there was a lot of fumbling and getting stripped of the ball. His 3 ball was also less consistent (37% this year compared to 43% last year). Assuming he splits the difference for his career that is still great. At this point, I am just having a lot more trouble projecting what he is going to be. There were very few games this year, where I thought "This guy is going to be a superstar and cornerstone of the team". Maybe he will be, but I feel a lot less confident in that after this season.
IMO, if the price for AD is Tatum and Brown, you do it (assuming KI stays). Both may be really good players in the future, and could have a half dozen or more All Star appearances between them, but they are not superstars, nor do I think it is realistic to project them to be. Could one or the other turn out to be? As KG said, anything is possible. But AD IS a superstar. I think while this season provided a lot of uncertainty for the fans, it provided a lot more clarity for DA, and what he needs to do in order to become a true contender.
