of the stadium, visible to both players and fans to note the official time between the ready-for-play signal and the snap of the ball. If the defensive team commits a foul during a failed extra point attempt, the try is replayed and the offensive team has the option to either have the distance penalty assessed on the next try or the ensuing kickoff. If the defensive team commits a foul during a successful extra point attempt, the penalty will be assessed on the ensuing kickoff. Players cannot grasp the facemask of an opponent. The penalty for an incidental grasp of the facemask is 5 yards (this penalty was repealed in ). The penalty for twisting, turning, or pulling the facemask is 15 yards. A player risks immediate disqualification if the foul is judged to be vicious and/or flagrant. A defender is prohibited from running or diving into, or throwing his body against or on a ballcarrier who falls or slips to the ground untouched and makes no attempt to advance, before or after the ball is dead.

From 1947 through 1975, the official coin toss was held thirty minutes prior to kickoff, and a simulated coin toss was held at midfield three minutes prior to kickoff to inform the fans and media of the outcome of the toss.

Every other NFL team played a home-and-away series against the other members in its division, two or three interconference games, and the remainder of their 14-game schedule against other conference teams. As a member of the AFC in 1976, Tampa Bay played the other 13 members of the conference, while Seattle did the same in the NFC. The 14th game, played in Week Six, was Seattle’s 13–10 win at Tampa. Starting in 1970, and until 2002, there were three divisions (East, Central and West) in each conference. The winners of each division, and a fourth “wild card” team based on the best non-division winner, qualified for the playoffs. The tiebreaker rules were
