Maybe Danny knows Smart isn't as good as everyone on here think's he is and wants to trade him while his Value is still pretty high
I would say there is some truth to that statement.
Don't get me wrong, I think Smart is going to be an extremely valuable player in this league - the type of player who increases wins everywhere he goes, and the type of player every team wants to have.
But I have my question marks as to whether he will ever actually become a true star player.
The way I look at it, there are four categories of stars:
Category A - Franchise PlayersThese are guys who you could make an argument for being top 5 overall in the league, and top at their position. Guys who are almost certain to go down in history as an all-time great once their careers are said and done. These are guys who are so good that you don't even bother making trade inquiries, because you know that (unless they force their way out via free agency) they are are untouchable. Includes players like Chris Paul (in his prime), James Harden, Lebron James, Kevin Durant and Anthony Davis.
Category B - SuperstarsThis category typically includes the guys who arguably rank top 20 in the NBA (top 3) at their position. These guys are not quite Franchise Players, but are right on the borderline. Guys like Demarcus Cousins (Borderline Category A), Dwight Howard, Kevin Love, Lamarcus Aldridge, Carmelo Anthony, Paul George, Russel Westbrook, Stephen Curry (arguably Category A), Kobe.
Category C: Clear All-StarsThis category basically includes all the guys who are among the top in the league at their positions, but not quite at that elite/superstar level. Guys like Marc Gasol, DeAndre Jordan, Blake Griffin, Kawhi Leonard, Jimmy Butler, Klay Thompson, John Wall, Damian Lillard.
Category D: Boderline All-StarsThis category includes all the guys who are right on the borderline of being an All-Star. They barely make (or barely miss) being voted to the All-Star game and don't really put up the type of statistics you expect from an all-out star, but are extremely valuable to their teams none the less. This includes guys like Al Horford, Greg Monroe, Andre Iguodala, Gordon Hayward, Luol Deng (in his Bulls days), Zach Randolph, Paul Millsap, Tyson Chandler (Dallas days), etc.
Looking at Smart, I think his ceiling is that of a Category D star - somebody who could be a nice complimentary (second or third piece) on a championship contender, but not somebody good enough to do the carrying himself.
So if you are Danny and you have a chance at getting a guy who is a Category C (or better) star but the condition is that you need to give up Smart...then I think that no matter how much you love Marcus Smart, you have to make the deal.
I think that's exactly what Danny's mind frame is, and I don't think he'd trade Smart unless he could get AT LEAS another category D star (preferably Category C or higher) in return.
Looking at Rozier, I feel like he has the potential to become a Category C star - I could see him becoming a Damian Lillard / Jimmy Butler caliber player. I don't see that type of potential in Smart...but even a Category D star is still extremely valuable, which is why I would like to keep him here unless there's a chance for a significant upgrade.
For comparison purposes, I see Sully and Olynyk maxing out at Category E (good starter) and Bradley and Bass maxing out at Category F (solid starter) player.
