The Ed Thorp Memorial Trophy was established as the league's award for the NFL champion, and was awarded through 1967. The host team for the NFL Championship Game would now alternate between the two divisions, with the Eastern Division champion hosting in even-numbered years, and the Western champion hosting in odd-numbered years.
Major rule changes
- A hand-to-hand forward pass made behind the line of scrimmage that becomes incomplete (hits the ground before it is caught) is to be ruled as a fumble.
- Incomplete passes no longer result in a five-yard penalty
Note: Tie games were not officially counted in the standings until 1972.
