It'll be interesting to see how E'twaun shoots in the pros. He was a very streaky shooter in college. It was a big reason (the main reasons of course being his lack of size and athleticism) he slipped so far in the draft.
I've said this a few times: I think he can have a Roger Mason, Jr. type role and career, but it all depends on that jumper.
His shooting %s in Europe have me optimistic. Small sample size, but a good initial indication that he can maintain a consistent level of efficiency in a smaller role than he had in high school and college.
