I can't remember what exactly lock said, but I remember him saying Hayward had a high turnover rate out of pick n roll.
You're right. I heard the same thing. He TOed the ball 30% of the time, which is quite bad. Interestingly enough, Burks had the best TO% of any of our guards on the P&R. The problem with Hayward is his ability to finish at the rim on P&R's, and thus he has a tendency to force the pass since he prefers to pass or jump into the air before even knowing where he's going to throw the ball since he seems a bit uncomfortable driving the ball in the half-court offense. We've all seen his great passing, but he needs to get comfortable driving the ball and be happy to dribble through like Nash or Paul (or any good PG for that matter), kick it out without jumping in the air, or be able to finish at the rim in the half court offense at a clip above 43-45%. So I agree he has some work to do to be able to run the P&R efficiently.
