It almost feels like Ochai spent too many years playing college ball. He probably has a lot of defensive bad habits that are hard to shake now that his opponents are much better, bigger, stronger and quicker. Hardy even hinted as much in some interview. Despite his athleticism and length, he plays really small - probably because he didn't really need to be playing big at Kansas. Being 6'5'' was enough on the wing.
Still, I've come around on this kid and I'm eating my crow. He seems to be a willing learner and has all the physical tools to be an effective wing in this league.
