"It's more than one key. It is just completely different from anything we've ever ran here," says [Josh McNeil]. "For the last couple of years, we've run just a straight-up, downhill type of run game -- just man-on-man, who can root the other one out of the hole. We still have that, but now we're stretching teams. We're cutting people off. We're letting our backs make cuts and getting people out of position, and the back only has to find a crease instead of us having to push people back 5 yards to make a big play. That's really a big change."
