One positive, imho, about Yabusele having spent this year in the CBA, is that the assistant coach for the Sharks was Brain Goorjian. For those who don't know who that is, he is an American, but most famous for his massive success as a head coach in the Australian National Basketball League. He is considered to be a brilliant basketball coach.
I'd like to think that his presence on the staff of the Sharks had a lot to do with why that team was chosen for Yabusele to be stashed on this year. Yes, the level of competition is not much better than a mid-level NCAA conference. But he almost certainly got nothing but a positive coaching and development experience out of his time there.
Similarly, I think the opportunity for Zizic to get several months of time under Coach Blatt during his stint in the EuroLeague is a fantastic development opportunity.
Both these guys are peer age with kids coming out of this 2017 draft, but instead of having spent this year playing schoolboys under NCAA coaches who ... often aren't really all that vested in the development of pro players , they have spent the year playing in professional environments playing with and against mostly older pro players and under highly respected pro coaches. I expect both to be far better prepared for life in the NBA when they finally show up as rookies than the typical NCAA rookie.
