it is a concern . Playing 59 games, in a lockout shortened season with no proper training camp and a really tight schedule is a good test of that durability though.In fact it's a good way to get injured. NBA players were falling over with all sorts of serious injuries. Spitter's were minor in comparison. Last season was his first real test of playing meanningful mins regularly. I think he deserves a pass. I guess this is part of that evaluation process of Splitter for the FO and coach POP going into next season.
There was an occasion in the WC finals that POP tried to use them together. It had Tiago commit one of those defensive mistakes i mentioned earlier. It resulted in a Tiago benching on the instant. My first reaction was POP you hardly tried them during the season. He did the same last play-offs with Tiago. Wanting to use them together at the most important part of the season(play-offs)says to me the willingness to use the combo is still there. The mistake has always been on POP for not getting them familiar with each other during the season. To be fair to POP, the shortened season didn't help matters.
TIago gettting his first full traiining camp will certainly help this situation. Pop's going to have all the practise time in the world, meaningless pre-season games plus a full spaced out season to intergrate them. It might come at the expense of a few losses but even coach know you gotta learn the hard way.
As i've always stated, if POP continues to use Tiago purely as a back-up to Tim and nothing more moving forward. If there is no increase in mins and a loosening of that leash in developing Tiago. Then the Spurs should look into trading him for the right deal. That is the most pressing question right now going into next season.
