I think Mudiay will be a better pro because he seems like a good kid who will work really hard, but I don't think it'll haunt Sacramento.
PG is by far the deepest position in the NBA. A somewhat like replacement for a guy like Mudiay is typically available at the deadline every year (Dragic, Knight, Jackson). Meanwhile guys like Mozgov are going for a kings ransom because there just aren't a whole lot of 7 foot tall people on earth and WCS has the defensive potential to be a monster guarding pretty much out to the 3 pt line.
