By choosing the veteran over the rookie, trading away their 1st round pick shows the Hornets are less concerned about player development, and more concerned with building off of last season. Whether you agree with that depends on your perspective.
Attempting to understand why the Charlotte Hornets traded the 22nd pick in the NBA draft to the Sacramento Kings for Marco Belinelli requires looking at it from different perspectives. The Hornets clearly weren't fans of this draft class, and if there were one or two prospects they were sold on, they wouldn't have dealt the pick before the draft started.
