The whole point of getting Webber was to take pressure off of Iverson. Everyone, including AI knows this, and you can bet Cheeks knows it too.
I fully expect to see the Sixers designing offensive plays around Chris's capabilities. If Webber can shoot adequately, teams will be hard pressed to cover him, contain AI and keep Igoudala and Dalembert from embarrasing the other team with easy baskets.
It shouldn't take much convincing, as once the players see how much easier it is to score- particularly AI, the team will come together nicely.
Until Webber came along, AI didn't have a reliable option on offense. No one who was really an automatic 2 or a bucket and a trip to the line. Dalembert would get the easy ones, but they still had no one to dump it into.
O'Brien insisted on using him at the top of the key, instead of in the post. This was just stupid. Webber can pass out of the post if he's guarded, and will force the other teams to keep a man on him. With Dalembert near by, other teams will have to respect his ability to score as well. Keeping the big men in the post occupied, makes them a step slower in intercepting AI and AI comming down the lane. If they leave too early it's an easy score for Sam or Chris. If they clog the lane, Korver should be open.
At this point in their careers, these guys want rings. Even if they play their best the odds are against them with Miami, Indiana and Detroit, even Washington has enough decent players. If they're going to have any chance at success, they're going to have to work very hard in the games and at practice.
I'd say that this gives AI the incentive, plus he's not the petulant child he was when he first came to Philly. He really has cleaned up his act and made great progress as a human being. Cheeks is probably the one he could relate to best out of all the coaches he's had.
The proof will be in what happens as they start to work together. The Sixers have a chance to be a decent team this year, and even better next year. Last year was a real dissapointment, and the trade disrupted any continuity they had. This year should be different.
