Personally, I don't understand why we need a Stockton PG right now.
Why not a good shooter? For one, we need a shooter. Secondly, the NBA has changed to a more scoring type PG.... And thirdly, Burks and Hayward can create. In fact, I want to see more time and spaced dedicated to their ability to create. What's wrong with using Burks/Hayward as Ginobli/Harden in pick and rolls with our bigs?
I understand we couldn't do this when Keefe and Bruss were our SF/SGs.
But Burks and Hayward are great athletes and thrive when the ball is in their hands. They're not catch and shoot players. That's not their strength.
If anything, we need a PG who can nail the shots that Hayward/Burks create. I'm not sold in Hayward's or Burks nailing wide open shots created by PGs. They're better off creating, driving, and getting to the FT line rather than playing as Korver or Matt Bonner waiting to receive a pass.
So play to the strengths of our team. Get a PG that can shoot and create (decently). Then use Burks and Hayward to create and exploit matchups. If we had a number of shooters and catch and shoot players who couldn't create then a PG like Marshall would make sense. Unfortunately, we're a team of slashers, drivers, and creators rather than shooters.
Play to the strength of our team. Get a PG that can shoot.
