I don't think there are enough jobs in the European league to absorb many players. Star quality is fine, but a lot of these teams are very nationalistic (at least it seemed that way during the FIBA championships) and they are still working on raising public (fan) interest. Throw in China (they probably have more money) and you might lose a few more players. The owners probably have had studies done on this before they pulled the trigger, and have said they are willing to chance it.
