First, don't get me wrong - I like Marcus Smart. I am not sure about the Rondo, Bradly, Smart synergy - but if Rondo is moved, I can see Smart as a solid starting PG in our future.
That said, Vonleh is:
A. Huge
B. Mobile
C. Soft hands
He is putting up about 9/9 in the SL in about 27 minutes. His shooting is aweful - but it will improve since we know he can shoot. Big men take longer to develop - and SL is always dominated by guards. Gurgui Deng was really bad starting last season and now looks like a legit two way center.
Could Vonleh have been our Center of the future? He is basically Andre Drummond Size, and more skilled (though less athletic).
