I suppose that depends on what you're expecting. If you're expecting him to come in and be a threat to be a double/double that seems doubtful this year and maybe ever.
To me he's playing a similar role on that French team that he would here where he's an afterthought on offense but does have some posts moves and isn't afraid to shoot. What I would worry about is the defensive end. He's no threat to block a shot. Perhaps that will be mitigated by Doc's defense of packing the lane but he's not really stopping anyone who gets into the paint. Is he a poor rebounder or is he deferring to the better rebounders on this French team? Seems more like the former as he doesn't win a lot of one-on-one battles. He has a big body, seems to have a good basketball IQ, seems to play hard, and still super young. If we're lucky he's an under the rim Leslee Smith without the injuries. To me he seems like our backup center who plays 10-15 minutes a game and hopefully he grows skills-wise to make up for his lack of explosiveness.
I think if he had been practicing with the rest of the team in front of Rothstein that Jon wouldn't have listed him as a starter though I could be very wrong about all of this.
