[...] Mitchell spent his first professional season with the Rio Grande Valley Vipers of the D-League, averaging 9.8 points and 9.0 rebounds in 26.9 minutes per game. The free throw stroke still hasn't come back, as he shot 48.9% from the line, and although Mitchell took 41 three pointers on the year after taking only 11 his entire college career, hitting only 9 of them doesn't make him a stretch threat. Not yet, anyway - another year of working on that, like Eduardo Najera once did, and Mitchell's in the frame.
