In Chicago, for the games that I've seen, Korver would be in the game with the sole purpose of taking a game tying or game-winning 3. They pretty much would let him spot up around the arc and wait for the ball. A lot of the shots he took were with the shot clock winding down, and being contested. I saw very little back screens for him, and very little movement period, just spotting up. I could be wrong, since I only watched a handful of televised games, but I don't see how it would be any different.
He's best used when he can come off of screens, quick-hits, moving the ball to the open man. His best season in Philly, he was allowed to score using different kids of looks. He was allowed to come off screens in a variety of ways, and get different kinds of looks. He also would get looks from being the trailer. But like I said, I've only seen a handful of games from each team with him, but the approach was different.
