An 1875 Harvard-Yale game played under rugby-style rules was observed by two impressed Princeton athletes. These players introduced the sport to Princeton, a feat the Professional Football Researchers Association compared to "selling refrigerators to Eskimos.
Despite these new rules, football remained a violent sport. Dangerous mass-formations, which involved interlocking interference, like the flying wedge resulted in serious injuries and deaths.A 1905 peak of 19 fatalities nationwide resulted in a threat by President Theodore Roosevelt to abolish the game unless major changes were made.
Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes.High school football games are 48 minutes in length with two-halves of 24 minutes and four-quarters of 12 minutes.The two-halves are separated by a halftime period, and the first and third quarters are also followed by a short break.
There are two categories of kicks in football: scrimmage kicks, which can be executed by the offensive team on any down from behind or on the line of scrimmage, and free kicks. The free kicks are the kickoff, which starts the first and third quarters and overtime and follows a try attempt or a successful field goal, and the safety kick, which follows a safety.
