Nice article comparing Jeremy and Kemba.
A few things I'd like to point out...
Jeremy's numbers are not true in the sense that he's been limited or should I dare say shackled and handcuffed for most of his career. Kemba on the other hand, has come in as a high draft pick and given the keys.
Also, not all turnovers are created equal and a high turnover rate is not always a bad thing or sign. See Magic, JKidd, Steph, and John Wall.
And JLin's turnover rate was at it's peak during Linsanity. However, I do agree this is an area where JLin has a room to improve still.
