I don't think this tells you much about the draft that you don't already know.
Marcus Smart
Noah Vonleh
Aaron Gordon
Julius Randle
All of those guys are said to be coach favorites - hard working guys who are highly coachable. If he (by some chance) slips to 6th you can throw Exum in to that list too, because every team official I've seen speak of Exum has raved about his maturity and intelligence.
I do think the concept of Danny avoiding a scorer is way off mark though. Boston is in desperate need for scoring, and Smart is the best scorer on that list. Even if Stevens wants someone who can defend - Smart has been very highly spoken of as one of the best defensive guards in this years draft. Leadership? Everybody who has known Smart seems to say that he has the ultimate winners mentality, is highly coachable, and is a great locker room guy.
Right now I have to believe that all the hints point to Marcus Smart as the #1 target for Ainge, but at the end of the day it all depends on what they see as their biggest need.
Do they want to get a guy who they believe will is the best player right now? If so it will probably be Smart or Randle.
Do they want the guy with the highest upside? If so it will probably be Smart or Vonleh.
Do they want the guy who will fit one of their major holes? If so it will probably be Smart (scoring) or Vonleh (rim protection).
I don't really see any scenario where Gordon becomes the most desirable option here. He doesn't really give the Celtics anything that they aren't already getting from Green and Wallace at the SF spot, and both of those guys are on extended contracts (hence are no risk of leaving in free agency). On the other hand Rondo and Bradley are both at risk of running either this year or next, so signing Smart would make a LOT of sense as insurance. They don't have a legit center, so signing Vonleh also makes a lot of sense. Sully is their most valuable trade asset and is a bit of a health risk, so signing Randle (and trading Sully) also makes some sense.
Unless Boston find a way to trade Wallace (or is set on trading Green) I don't see any real need for Gordon on the roster. He just doesn't fit anywhere.
