No i don't know more than the org. The Org also didn't know Randolph , White and T Will were going to be this below avg.
There is a reason its called a 10 day tryout.
But it doesn't mean you have to now sign them for the rest of the year. At least you can cut Randolph and get someone else.
This is what you don't seem to be getting, despite the fact that it's been stated about 15 times in this thread.
It is in fact highly likely that the "org" knew exactly what they were getting (they are experts in evaluating NBA talent, after all).
The issue is that these guys were the best talent available, and still are.
So far your one big counter-example is Dwayne Jones, who hasn't played in an NBA game since 2010. Even then he played in a whopping 2 games for a total of 7 minutes. There is no evidence at all that he is capable of contributing more than White or Randolph.
So basically what you are assuming is , you lose two key guys and replace them with nobodies? or practice bodies?
How does that help us maintain or move forward? Is the goal not to win it all?
I know realistically there is limitations of what we could of got during trade time , as we don't have much attractive assets and cant afford to lose anyone else on the team, but also if you look hard enough you could get more productive players. At least ones that make enough noise in practice to get consistent 5 minutes on the court. Doc at times i'm sure is worrying that Bass is not getting the rebounds , wilcox is not focused and would like to bring someone in from the bench that can just plain out get you rebounds. Give you a different look, maybe shoot jumpers, have some post skill etc.
Randolph has none of these qualities, outside of being an embarressment on court. DJ White prob hasn't shown enough in pratice to warrant time on court. Same said for T Will. Its no rocket science, you can see out there, he is losing balls left and right.
So the solution i have is, keep looking. Cut Randolph and/or White, plus if i were the celts i would waive T will and get a few players that can bring something to the table. Last time i checked NBDL is a more advance league than the China league. Dwayne Jones is pulling down 12 plus rebounds a game , being a decent presence in the paint and scoring garbage buckets.
