1972 NCAA University Division football season

• Kickoffs that land in the end zone untouched by the receivers are blown dead and the ball put in play by the receiving team at their own 20-yard line (touchback).
• Official time-outs are called for players who are "obviously injured." Previously, teams were charged a time-out for an injured player.
• Fouls committed by the team not in possession of the ball behind the dead-ball spot are enforced from the dead-ball spot.
• Jerseys must be replaced if the numbers are no longer readable. (Tear-aways were popular for backs & receivers, later prohibited)
• Mouthpieces are made mandatory starting with the 1973 season.

In 1972, only the Rose Bowl (Big Ten vs. Pac-8) and Cotton Bowl (SWC winner) had rigid conference tie-ins. Thus, Big 8 champion Oklahoma passed up an Orange Bowl invitation to play in the Sugar Bowl, while SEC champion Alabama passed the Sugar to meet Texas in the Cotton. For the first time, the Sugar Bowl was played at night on New Year's Eve, rather than New Year's Day afternoon. With two consecutive victories in the Orange Bowl, #9 Nebraska was invited to a third against #12 Notre Dame.

as the top three were from Nebraska & Oklahoma:

1. Johnny Rodgers, WB – Nebraska, 1310 points
2. Greg Pruitt, RB – Oklahoma, 966
3. Rich Glover, MG – Nebraska, 652
4. Bert Jones, QB – LSU, 351
