I thought about it and just none of them sound useful for this team
Really, the Spurs have Duncan, Oberto*, Elson, Horry, Bonner*, Butler, Scola* and Mahinmi*. That's up to eight bigmen who could be on the roster next year. And with either Butler or Mahinmi (or both) on the roster next season, there really isn't a need for a big.
Perhaps Fazekas if the Spurs view him better than Bonner but I don't know how much an international big would help this team anytime soon. Even if Splitter drops to 28, that pick wouldn't excite me ... much less Fesenko, Stanko or any other anko's the Spurs can find.
