Some of these guys are clearly not ready and will probably be inconsistent if relied on.
Rozier
Young
Hunter
Mickey
I see ppl bringing this up a lot. Esp. given that we have so many picks it seems that several of the above players will be gone.
Personally, I'm not so sure.
Rozier and Mickey are not going anywhere at least for the next season: Mickey was p good both in the d-league and in his limited mins with the team (esp. against Utah);
Ainge defended his decision of Rozier just the other day on an interview, where he (subtly) alluded to the fans getting angry with Nash getting picked at 15 while he was the coach of the Suns (Rozier was picked at 16) - you can find this at the end of the audio interview here (not mentioned in the text summary)
http://boston.cbslocal.com/2016/03/02/celtics-offense-danny-ainge-toucher-and-rich/About Young and Hunter: it is true that they had disappointing seasons, but, look, Young is only 20 yo, this means he could well be drafted this year...
Per Hunter fans had to great expectations after the summer league, Larbrd33 had made at the time a nice table showing that good numbers in d-league do not immediately translate into NBA results, but I do not think the message got across.
Even if they wanted to trade them now, they would have to give them almost for free a la Dwight Powell, and I do not think DA values them as little as a 45 pick who ended in Boston by chance.
They will both probably at least one more year with the team.
Now, they might have to move some of the above around a la Marcus Thornton Jr to fit the magical number 15 for our roster. But I do not think they are getting traded or let go so soon.
