It's amazing how different the run game looks when you have a RB that has good vision and looks to press the edge. Dawson has been calling the same stuff all year, the major changes to the run game of late is Pringle and some well designed gadget plays, plays that give the defense something else to think about.
Pringle has shown that this run game can work, if you are looking to break big plays, instead of pounding teams into submission. Fletch is a pounder, Marty is a pounder, Lyle just doesn't seem to have the vision right now. Pringle is a pure runner.
