I think Oggie's shortcomings on defense cost him time. Groce also always emphasizes how the guys practice and I suspect this did not bode well for a kid in a new country and new system. The Zips system is much more up tempo and physical when what he was likely seeing in Europe. Also, Groce's rotations tend to shrink as the season wears on and he ended up as the 10th or 11th guy in a 9 man rotation.
