I prefer OLB's blitzing and run more zone than man to man (especially in passing situations) Look at your strengths on D. If you have a quality OLB then look at using him. Especially if he has good speed and acceleration. I shift my line a lot and constanty move my DT around (I mainly start my control with a DL and switch accordingly to who has the most pressure.) Also look at the various D plays. Using a nickel and dime is better suited to passing (dime especially) but they are weaker when it comes time for the run. Plays with a 2 designate good D on short pass plays, 3 means middle range and 4 is for long range. So if it's third and 3 I probably wouldn't be running a dime 4 play. Hope this helps...
