I don't mean to rip on either guy, but BP and DG are two different point guards. BP is almost like a shooting guard out there, he's just trying to run the offense and take the open shot, not to create anything. DG is a slasherit and creator. He's going to have more turnovers partly because he's a freshman, but more because he is a creator on offense and IMO because he needs to learn when to take the shot himself and when to dish it off. They're two different style players that each bring something different to the court that ISU needs.
Neither were good today. The issue with BP is look where he sets the offense..no dribble penetration means defense is all over him. DG has the upside to penetrate, but seems lost when he does.
