First of all, regular season games should not have overtime. It’s a tie. Live with it. You had 60 minutes to win, and you failed. There’s nothing wrong with a tie in the standings, the rules are fine with that. If there is no regular season overtime, teams will put in more effort to try to win the damned game instead of “playing for overtime” and there will be fewer games that tie at the end of the fourth quarter.
Of course, when you must have a result in the playoffs, a win must be obtained. Play another period. Full fifteen minutes. Don’t flip again to see who gets the ball, just continue. NFL football is a TIMED GAME. It’s not sudden death. Why change the entire concept of how the game is played for an overtime period? It’s ridiculous and unnecessary.
This is just another way that American sports are ruined by the television networks. I’m sure the sudden death overtime rules were the invention of a TV executive anxious to get the game over with.
