Here are the teams not in 2k17 that were in 2k16 as far as I can tell, unless team names have changed (I don't follow Euroleague):
Cedevita Zagreb, Croatia
Dinamo Banco di Sardegna Sassari, Italy
Limoges CSP, France
Neptunas Klaipeda, Lithuania
Nihzny Novgorod, Russia
PGE Turow Zgorzelec, Poland
Strasbourg, France
My guess is that there are licensing issues with these teams and that's why they're not available this year.

There will be less teams in euroleague upcoming year as the tournament format changes to something similar to NBA (all teams playing each other twice in regular season).
So far those teams were made as lazily as possible. Basically just logos, jerseys and "auto-generated rookies" quality of players details. Waste of a license in creating them.
Although I do watch euroleague games, I won't care about its content in nba 2k games until it got proper attention to details and gets incorporated to some game modes ( playing some euroleague games in MC before moving to NBA would be really cool).
If they put the time in to make these guys look accurate, have the NBA teams with rights to overseas players down pat so that you can trade their rights, try to sign them away from their teams etc. then sign me up for some of this. Until then, these teams are obsolete and just a quick cash cow move for euro fans.

Wait, you misspelled the teams name:
It is Cedevitz Zagreb (I'm joking...but it's an evidence for not much effort on 2k's side, that Cedevita Zagreb is misspelled for 2 games in a row...
I have a feeling we'll see a few new classic teams. At least that's what the hidden '06 Kobe model in 2K16 would indicated.
Also, we will probably get a few national teams along with Team USA and Australia's national team.
