And this is why you don't want to draft Pekovic with a 1st round pick, not even in the top-5.
On the international players issue, I think it's definitely something that will happen frequently - and one can already see that trend: none of the foreigners projected to go in the late 1st round are top players in Europe, far from it. A middle of the first round rookie contract is not attractive for good European players, as they can make plenty more money in Europe. I guess that, as Who states, a lot will depend on each player star potential: someone like Rubio, who has superstar potential, will join the NBA; guys like Splitter and Pekovic, who are superstars in Europe but that probably wouldn't be more than solid starters or borderline all-stars (best case scenario) in the NBA, will prefer to stay in Europe, at least for the best years of theirs careers.
Some rumors I've heard: Spurs are trying to sign CSKA's guard Siskauskas (IMO, the best player outside the NBA). Houston seems to be in the race as well. Gallinari is considering resigning with Milano, even if he's drafted in the lottery (here's the trend again).
ps - oh, and I'm sure that Rudy wouldn't be making more money than Splitter, had he stayed with Badalona. Tiago will probably be a top-3 player in Europe salary wise.
