once they start stopping the tosses, stretches, etc. then start using dives and u should usually get + yardage pay close attention to where the LB's movement is after the snap. if there all blitzing to one side, this may sound strange but run a stretch to that same side, and sometimes u can break a tackle or 2 and your off to the races because there is no one on that side because of the blitz. if all else fails, run a few HB screen passes in running formations to catch your opponent off guard. let them pick there poison they can't contain them all.
