Splitter looked good. Not the type of player I was suspecting considering how he was hyped but a solid role player. He's not Scola, but he'll help the Spurs.
Offense - can score in the post but takes too long for him. That dribble, dribble, dribble approach (announcer called it accurately as a 'Charles Barkley') doesn't work in the NBA. And again, that was on a lighter opponent in LO (who he did abuse). Didn't do much against Chandler. He moved very well off the pick/roll.
He'll do the dirty work on O but he's not a scorer. Didn't show a jump shot either.
Defense - Solid post defense (although Team USA doesn't have any good post players) but he'll be attacked and pick up a lot of fouls next year. Good help defender but not NBA-elite size so he's not going to block a lot of shots. Not going to get a lot of steals like Nene either.
My guess on next year - an Udonis Haslem-like impact. 25 min, 9 pts, 7-8 boards, .5 blocks per game.
Impact - it helps SA in that they have another big defender so its not just Duncan. He's not great but solid, and that may keep Duncan's legs fresher. But he's far from a savior or championship piece. Just not the offensive threat. But considering the price paid, he wasn't expected to be.
