I'd like to leave aside the question of work ethic, and shorten the OP's question:
Did drafting Young and his progress to date affect our draft this year?
The answer has to be yes. In spite of his tender age, he clearly does not look like the prospect we all had hoped for. He may get there, but it will take some time. Meanwhile, Ainge drafted 3 guards and a forward. RJ Hunter is particular plays that wing spot where Young plays. Was RJ simply the BPA at that position? Perhaps but then what about Thornton in the 2nd round.
No it doesn't. Ainge knew dang well that Young wasn't going to contribute much in his rookie year, he struggled finding a role on the big club but dominated in the D-League which is pretty much what they expected. They wanted Young to know that he wasn't going to be gifted anything, and any opportunity he got was going to have to he earned. It seems like it worked, because by all accounts he's been working as hard as anyone this summer. And him developing that work ethic and drive is more important than anything to his development.
The guys we drafted this year had NOTHING to do with what Young did or didn't do last year. Since our rebuild started, Ainge's picks have made it clear that he's looking for guys who have ASG potential and up-side in the middle/late 1st round. RJ Hunter was picked because we need shooting, and he has far greater potential than anyone else we could've picked at #28. James Young has always been viewed as a developing wing and not a guard anyway, hence why he's added on so much muscle. Adding Hunter has very little to do with the development of James Young and Thornton was only taken because he agreed to play overseas and not take up a roster spot if we drafted him. Stevens and Ainge will give Young an opportunity to seize this season for all the work he's put in. Let's see what he does with it, and not condemn him for not providing much as a 19 year old rookie on a deep roster.
I really can't believe some of the folks around here really think Young could be "on the bubble" during training camp. That's never gonna happen. We have a desperate need for wing scoring and a 20 year old SF prospect with serious scoring skills and a telnet level high enough that rival executives said he would've been drafted top 10 in this past draft. The idea we would just cut a guy like that is ridiculous. Especially when were in desperate need of star players. Jones will be cut or Turner traded for a bag of chips before that happens.
Young players, especially 19 year olds, need time to develop.
