Fielding Yost had a problem. After four years of dominating college football many other teams had learned his speed-'em-up and spread-'em-out offense, and were coming up with new ways to use the attack. Single-wing football was taking over, and the old way of matching seven players on the offensive line with seven defensive linemen was starting to get run around. The guy who solved it for him was center Adolf "Germany" Schulz. Rather than limit himself to taking on interior linemen when the ball kept going outside, Schulz stepped back, ready to launch himself back at the interior if need be: If you're wondering where's the safety, he had to hang way back in case the offense punted. It wouldn't be the last time defenses learned to counter offensive innovations by pulling back box defenders. S/O to Iowa State for finishing 22nd in the country in Rushing S&P+ while employing a 4 man box as often as possible. pic.twitter.com/iwrd1BfsfN Seth Galina (
