Screens serve different purposes in different situations, so they are not all the same. If you have a slow shooter that needs help getting open, then you need a wide set screen designed to take out the defender. In a pick and roll, the purpose of the screen is to get the screener inside position on his or her defender, so all you need is a bump and a seal.
I don't like where we run our pick-and-rolls, because when the screen happens at the free throw line, there is going to be help defense on the lob to Carlton, making that a very tough catch for Carlton, who is not a premier athlete.
