Ready: More than two years removed from a devastating knee injury, Livingston showed in a late-season audition he's healthy enough that a 2.38 career turnover-to-assist ratio would be an asset as the Thunder's back-up point guard. The former No. 4 overall pick, Livingston, 6-foot-6, can post up smaller point guards. He averaged 3.1 rebounds and nearly 1.0 steal a game before the injury. ... or not:Even before Livingston suffered a severe knee injury, he was hampered by injuries. In his three seasons with the Clippers, Livingston missed about as many games (111) as he played (145). Livingston also must improve his perimeter shooting. He made only six career 3-pointers and shot 44.0 percent with Los Angeles.
