It's unlikely that you will get to the quaterback using linebackers to blitz on a playaction, most playactions are roll-outs, so that refers to drifting in the areas where cornerbacks would play, therefore, try running cornerback blitzes in which the middle of the field is covered in zone by ur linbackers/safties, and allow the cornerbacks to get the sack, heck if u play user as the blitzing corner back and creep in a little closer then where they start from, you might be able to get him as hes faking the handoff...just a tip
