Davis Bertans, probably the most NBA-ready of all the Spurs' draft-and-stash players, is about to be bought out of his contract with Laboral Kutxa (aka: Deportivo Saski-Baskonia), according to EuroHoops. PATFO will reportedly be offering him a minimum contract to come to San Antonio next season.
Nothing is official yet, but things are moving for Bertans to be a Spur. If you're not familiar with him, take a look at the excellent profile Warren Yiu wrote for PtR last month. We'll post more concrete info on Davis as soon as it's available.
