Looks like the wait for Tiago Splitter might be over.
According to Tubasket.com, the San Antonio Spurs will sign Splitter in July when the NBA permits off-season signing:
Los San Antonio Spurs anunciarán el fichaje de Tiago Splitter en julio, cuando la normativa NBA lo permita.
If true, the Splitter would address the largest need for the Spurs — a legitimate big-man to play along side Tim Duncan.
