The 46 defense is an American football defensive formation, an eight men in the box defense, with six players along the line of scrimmage (4 playing line technique, 2 in a linebacker technique).
 There are two players at linebacker depth playing linebacker technique, and then three defensive backs.
 The 46 defense was originally developed and popularized with the Chicago Bears by their defensive coordinator Buddy Ryan, who later became head coach of the Philadelphia Eagles and Arizona Cardinals.

Prior to the first season of the National Hockey League (NHL), which commenced on December 19, 1917, there had been many seasons of ice hockey played by various amateur and professional leagues, often held contemporaneously, going back to the 1880s, to which the NHL can trace its roots.
 Below is a list of pre-NHL seasons by ice hockey leagues that are precursors of the National Hockey League.
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 farther downfield.
 The formation was created by Minnesota 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 was still considered viable.
 Yet 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.
 Further, 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.
