NBA projection: The biggest question with Hartenstein is really where exactly does he fit in the evolving NBA. We do still see cases of traditional bigs finding roles on teams (e.g. Willy Hernangomez). However, it is completely up to Hartenstein how much he will be willing to develop and work. If his offensive game continues to become more refined, there is no question that Hartenstein’s services will be in demand by NBA teams. Backup centers with height are always a good insurance policy for teams to have on their roster.

2016-17 Season
Hartenstein made his debut at the senior professional level this year with Zalgiris Kaunas in the Lithuanian LKL and Euroleague. As a member of Zalgiris he has played a bench role for the most part. He joined the German national team at the FIBA U-18 Euro Championships in December and helped the team finish in 4th place. In April, he participated at the Nike Hoop Summit where he scored 10 points.

Reminds me of: Nikola Jokic

What Insiders Say
Stefanos Makris,
“Hartenstein is one of the best bigs of his generation in Europe. His combination of size, skillset and versatility is difficult to ignore, since he can become a great inside-out player. He is still a work in progress though and he needs to continue working in all aspects of his game.”

Carl Berman, NetScouts Basketball
“I saw Isaiah play several years ago at the Jordan Brand Classic in Brooklyn. After seeing him at the Nike Hoop Summit in April he's clearly not the same player, which is both good and bad. He's filled out quite a bit physically which limits his previous explosiveness. But he's also grown and is now a true center with solid passing and rebounding skills. He's still athletic and while his shot is a work in progress there's always a place for a 7-footer with skills in the NBA. Being a lefty doesn't hurt either. The Jokic comparison might be a good one down the line."

Jonathan Givony, Draft Express
“Hartenstein may very well turn into a threat from NBA three down the road, but he showed that he has quite a bit of room to improve in that regard. His overall skill set offensively could use some polishing. With that said, Hartenstein has NBA tools to fall back on at 7' 1 with a great frame and impressive mobility. He competed all week long, playing only a couple hours from his hometown of Eugene, and proved that his time with Zalgiris has certainly helped him from a toughness standpoint. Hartenstein may not be the ultra-skilled stretch four man he showed flashes of in the past, but there's certainly room in the NBA for centers with his size, strength, aggressiveness, rebounding ability and potential skill set.”
