Yup. This is part of the problem. They don't wait long enough to make contact. More often than not, there is no pick (no physical contact), there is no roll (can't really roll without the screen), and no pop. The guard gets doubled and picks up his dribble, playing into what the D is trying to do.
they could run slip screens, have the guard draw the double team and move it higher away from the lane, pass to the guy who set the slip "screen" and have him pass to the opposite wing, as hoops upstate suggested. We have the shooters to run that play. Marek could be used as the trigger. Maybe that's what they are trying to do.
