He went from too good for summer league (which wasn't true even the first game), to looking like a guy that hasn't improved at all. Browns biggest issues moving will be his handle and his shooting. Just doesn't have much of a clue in the half court unless he's going downhill.
I'd consider this mildly concerning for the long term. No nothing, but not good either. For the short term, I laugh at the idea of him being a starter this year (even though fans will point out that he did well in a few starts last year). Big difference between a few spot starts and being a true starter).
