7–1–2–1 defense

Wikipedia Overview

The 7–1–2–1, or seven-diamond defense, used seven "down linemen", or players on the line of scrimmage at the time of the snap, one linebacker, two safeties relatively close to the line and one safety further downfield. The formation was created by Minnesota Golden Gophers coach Henry L. Williams in 1903, reputedly to stop Michigan back Willie Heston. By some accounts in the mid-1930s, the 7–1–2–1 was considered "almost obsolete" due to its weakness against the forward pass, whereas the 7–2–2 defense was still considered viable. However, Bill Arnsparger notes the use of the seven-diamond from the 1940s into the 1960s, as a defensive adjustment to the common wide tackle 6 defenses of the time. Furthermore, the form of the 7 diamond as derived from a wide tackle 6, with a more compact line spacing than the 1930s era 7 man lines, shows a marked similarity to the 46 defense of Buddy Ryan.
