The National Football League (NFL) is the largest professional American football league. Thirty-two teams from American cities and regions form the NFL. The league's teams are divided into two conferences: the American Football Conference (AFC) and the National Football Conference (NFC). Each conference is then further divided into four divisions consisting of four teams. Each team is labeled East, West, North, and South.

Each team plays sixteen games over a seventeen-week period during the league's regular season. Generally, it continues from September to December. At the end of each regular season, six teams from each conference play in the NFL playoffs, a twelve-team single-elimination tournament that culminates with the NFL championship, the Super Bowl. This game is held at a pre-selected site which is usually a city that hosts an NFL team. One week later, selected all-star players from both the AFC and NFC meet in the Pro Bowl, currently held in Honolulu, Hawaii.

Perhaps the biggest change to the game in 1951 was the return of the Pro Bowl Game. Dormant since 1942, the Pro Bowl Game was revived under a new format matching the all-stars of each conference at the Los Angeles Memorial Coliseum and on January 14, 1951, the American Conference defeated the National Conference 28-27. Following that game, on January 18, a rules change was enacted that said no tackle, guard, or center would be eligible to catch a forward pass (NFL).
