What he can do
With a very strong A/TO ratio, at minimum, Siva should be able to run the offense off the bench. In terms of performance, there isn't much difference between him and Michael Carter-Williams. Plus, his free-throw percentage indicates there might be better shooting than his college stats indicate, and his steal rate indicates he could do some serious damage on the defensive end, and that he can compete with NBA talent.
What he can't do
Well, he can't shoot, and he's short. At best, that projects to a backup point guard.
What Draft Express says
Overcoming a challenging early life and possessing as inspiring a backstory as any player in the 2013 Draft, Peyton Siva won a national championship and got to cut down the nets in Atlanta, putting the finishing touches on a terrific four-year career at Louisville. A player we've covered in detail at various points over the last five years, Siva still struggles with some of the same things he did as an underclassman. Nonetheless, he emerged as the undisputed leader of the Nation's best team in 2013, made some small strides as a senior, and brings some intriguing abilities to the table as a prospect.
Many of those talents are a byproduct of Siva's excellent athleticism. Though he lacks outstanding size for a point guard, he makes the most of his 6-1 frame and 6-3 wingspan with an explosive 41.5 inch vertical leap and tremendous quickness. On top of his physical tools, Siva plays with as good a motor as nearly any prospect in this draft.
What I say
The quintessential backup PG, Siva looks like a good bet to stick in the league. His steal rate projects very well at both ends, though his shooting will limit his effectiveness.
By my lights, this draft indicates the Pistons fully intend to re-sign Calderon, and they are looking to Siva to change the pace off the bench. I have no problem with that idea.
