You aren't following the draft very closely if you haven't noticed a Euro backlash. This year, if only Gallinari and Batum are picked, that'd be the fewest international selections in a first round since 1997. That's not an accident.
NBA GMs have always been fickle. There hasn't been a good international first round pick since 2004. Couple that with the growing difficulty in getting players out of Europe and those are the reasons why GMs aren't being as risky with international prospects. If Bargnani, Jianlian, Belinelli, Sene, etc. had actually produced early on, Gallinari would be a hotter name and Batum would be a lottery pick. On top of that, there would be other international players that GMs would want to take a flyer on.
This is definitely a down cycle in the NBA's confidence of the international player. But as is always the case, all it'll take is the next Nowitzki or Gasol or Parker to be selected in the first round and then GMs will once again be all over the international market.
