18. Tiago Splitter
Drafted with the 28th pick in the 2007 draft, Splitter, a Brazilian native, didn't make his debut with the Spurs until 2010. He's had little trouble transitioning to the NBA, however, averaging 6.9 points and 4.3 rebounds off the bench for the Spurs the last two seasons. Splitter's ranking may seem a bit high amid a crowded big-man market, but his per-36-minute averages (16 points, 9.8 rebounds, 1.2 blocks) hint at the 27-year-old's potential.
