I wish, and i mean wish, Canada would change the running system. He won't do it. That stupid little RPO and quick Jett sweep has been oh-so moderately successful in pausing the front 8 and so, Canada just won't do it.
But i think if they did keep Green in and replaced Chuks with Haeg and/or Dot with Finney, they could run the Shanahan outside zone blocking scheme one hell of alot more effectively than the inside-zone, up-the-gut running game right now.
i've seen plenty of times Najee was hit hard, looked to be stopped 3 yards behind the LOS and then dragged the guy with a lean for a 3 yard gain! Najee needs some room. Just give him 18 inches. Best way to do that right now - honestly - is to get him outside the tackle-box.
