Tiago Splitter B+
Defensively, Tiago Splitter was really good at protecting the rim. He's never been a shotblocker at any level in his basketball career, however he's showing that ability so far this year. His post defense against the Jazz wasn't very good, however. On offense, Splitter was really, really aggressive -- with mostly positive results. The Spurs need him to get comfortable offensively for Splitter to reach his potential and he appears to be making strides in that direction.
Kawhi Leonard B-
In the first half, Kawhi Leonard looked good. His movement on offense continues to be a plus. He was also a big factor on the boards and played fine defense. In the second half, Leonard experience a lot of growing pains. He got caught being too aggressive defensively a number of times and found himself out of position. He also made a handful of tactical mistakes on the defensive end, especially in transition. That said, there's no way the Leonard is going to learn on the fly without these types of struggles.
Matt Bonner B
Hey, compared to the first three games, Matt Bonner was pretty damn good. He actually pulled down three rebounds and hit his only shot. His defense was still sub par but his passing on the offensive end helped the Spurs get off to a good offensive start. Watching him closely, he appears to be favoring one of his legs. He had a knee wrap in the first half, which may be a hint that he's not totally healthy right now.
