I was going to start a thread on this, but might as well dump it in here.
Back in 05-06, Sloan ran a very jump shot heavy offense that didn't need a facilitator to rack up a **** ton of assists. I think the reason for his decision was the incredibly talented group rebounding he had - Memo, Boozer, AK, Harpring - who could clean up a lot of missed shots for easy put backs or resetting the offense as they did a lot.
Williams only averaged 4.5 assists per game. AK added 4.3 but he didn't do it in the way we would expect Hayward to this season. They only needed a point guard to dribble the ball up, pass to AK on the left wing, who waited patiently for the offense to develop a decent mid-range jumper. He got assists that way.
Matt Harpring played a huge 2 on that team. The way he was utilized is the way I'd like to see Hayward utilized by having him come off screens for jumpers with the ability to cut to the basket as well.
