I'm sure this has been mentioned before, but on the subject of former Spurs playing over seas, James White! played a little for Fenerbahce this year.
I've seen Splitter play 5 or 6 times, generally to encouraging results. He moves well in general, though I've seen him struggle a little with the likes of Marc Jackson (who spent a season or two in the NBA), and I seem to recall him struggling with Daniel Santiago as well, though that was much earlier in the season and my memory isn't the best. Both of those guys play pretty physical for the Euroleauge, so I wonder how Splitter will translate to the NBA.
