Perfection came with simplicity.
It was at once simple yet subtle, direct yet flexible. Every player was taught not just what he should do under normal conditions but how to respond to any unexpected defense.
The sweep had another meaning in Lombardi’s system: it was his definition of team, a play in which the offensive players had to think and react together, eleven brains and bodies working as one. “Everyone was important in the sweep,” said Ron Kramer.
It placed the emphasis on reading the defense and giving the quarterback fewer plays but more options.
