I read all these commenters coming out and saying how we need to make room for James Young or that he has trade value. I've watched this guy in the D-League when he got sent down and it's pretty bad. This guy can't even defend D-Leaguers he is so bad at defense. His biggest asset was his shot, but that has not translated at all to the NBA. He can't handle the ball at all. So in other words he's a complete liability when he's in the game. He is a rookie so he can obviously improve, but I'm being optimistic when I say he can be a nice bench player. If he doesn't make any significant jump into next year I wouldn't be surprised if he is out of the NBA in 2016-17.
You can't make this type of judgment call so soon with an 18 year old rookie. That's not realistic.
I have high hopes for him because his coach is always speaking how ahead of the curve he is at such a young age. He seems to have a high bball IQ, and now he just needs to put in the work.
It might be tough to hold onto him though, because it seems Ainge has this ship turned around in a hurry, and a piece like a 19 yr old Young could look good combined with picks, etc. in a trade.
For this reason, I don't see Ainge waiting around for his development. He's got a bunch of assets to get a 'now' player and I think a Vet, plus Young, plus some picks nets him a darn good player.
