I think there are a couple of good signs with picking Jonas.
For starters, some people thought BC would try to make this team better quickly because of his two year contract. Some said, because of that, he needs a good year in his last year, meaning get in the playoffs. I don't think the Jonas-pick, if he doesn't come over this year, is suited for that goal. And if we have another lotterybound year, it's unlikely even a good draft next year and adding Jonas would immediately result in a playoff place. So, maybe BC is really trying to make this team better in the long run instead of making the team better now.
I also agree with others on here that good centers are relatively sparse in the league. A good center is pivotal for having a good defense. From what I've read Jonas has good defensive skills. Regardless of what team (or position) AB will play on next year or the year after, the defense at the center position needs drastic improvement. I do consider this a change of culture, much more than the selection of a scoring guard like Kemba Walker. Not a change from European to (North) American, but a change to getting defensively capable players and a change from trying to get better now to getting really better, by drafting for the future; a change which already started midway last year.
And for some posters: Europe is pretty big and very diverse; most Italians (or Dutch like me) probably can't even point out Lithuania on a map, have never been there, have never met someone from Lithuania and don't know anything about Lithuanian culture and cannot name a single famous person in Lithuania. It's not like it's one big melting pot.
One last add: Jonathan Tjarks on realgm, who usually writes very interesting blogs, had a piece about drafting for mediocrity which might be applied to the Jonas-pick as well:
