Oh and in response to the OP...worst possible result for me would be taking Aaron Gordon at #6 and Saric at #17.
I know that this answer will probably shock a lot of people, but I have my reasoning. As much as people in today's NBA love athletic guys dunking all over everybody and wowing the crowds, I'm much more about substance than style. I'm absolutely convinced that Gordon (with is lack of jump shot, worse-than-Shaq FT shooting, skinny build and average height) make him an absolutely terrible fit on a Celtics team who's biggest needs are:
* Scoring - preferably a go to scorer, but a shooter at the very least
* Rim protection
* A good combo guard - becuase neither Rondo nor Bradley is guaranteed to be around two years from now
Gordon seems to me like the only guy who is projected to go lottery that cannot help in any of those areas.
* Wiggins: Capable scorer with the ability to create his own offense and potential to develop in to a go to scorer
* Parker: Exceptional offensive player who could scorer who could be a go to scorer from day one
* Embiid: Elite rim protector with potential to become an exceptional offensive center
* Vonleh: Can stretch the floor, can score in the post, has Has the tools to be a capable rim protector
* Smart: Capable scorer with the ability to create his own offense and potential to develop in to a go to scorer
* Randle: Potential to be a Zach Randolf type threat in the low post
* Exum: Capable scorer with the ability to create his own offense and potential to develop in to a go to scorer
* McDermott: At worst offers the skills of an elite shooter, at best could be a very capable scorer at the NBA level
Every one of those guys at least does something to fill a void...Gordon doesn't. His selling point is that he's an outstanding athlete and a lock-down defender who loves to run in transition - Jeff Green already gives us this. Why waste a pick on a guy with a completely redundant skill set?
Sure it wouldn't hurt getting a backup SF to replace Wallace (who may or may not be healthy again next season, and is kinda useless even if he is healthy) but is it really worth wasting a #6 pick in a stacked draft on a backup SF? We could fill that hole with our #17 pick. Better yet, we could probably fill that need using a second round pick on a non-guaranteed contract or a or cheap vet-min free agent signing.
As for Saric, I like his skill set and wouldn't mind picking him up in the draft if we can get him with #17...but only if we are picking up a nice player at #6 who will immediately help to fill a void. If we use #6 to pick a redundant player like Gordon, then use #17 to pick Saric (who we won't see in Green for until 2016) then we coming out of one of the promising drafts in years with...pretty much nothing.
So that, to me, is the worst possible scenario.
