Ive found that im forcing alot of fumbles since ive started doing this. I will go into quarters or 3-4 and pull lawrence taylor off the line than move him opposite to the HB. I find this is excellent for causing fumbles. I shade the crossing routes, spy the Qb or go after the running back and his hit power when someone is on the run just wrecks people. 400% increase in game changing fumbles. Also good for the toss as you can go wide and force the running back to cut inside and get nailed.
