Football in India
The Indian Super League, a tournament just recently recognized by AFC or FIFA, was founded in 2013 in an effort to make football a top sport in India and to make Indian football a major player worldwide. The league operates along the lines of the Twenty20 cricket Indian Premier League, and Major League Soccer of the United States. Unlike the vast majority of football leagues around the world, the ISL does not use the promotion and relegation system. Instead, it uses an American style franchise system in which ten teams were specifically created to participate in the league. Each team in the ISL is composed of players from I league or state league, apart from the foreigners who may or may not be a part of the I league. Recently it was recognised as the second national league in India, which means ISL champions from 2017–2018 leagues will be eligible for an AFC Cup qualifying slot
National Football League
The National Football League (NFL) is a professional American football league consisting of 32 teams, divided equally between the National Football Conference (NFC) and the American Football Conference (AFC). The NFL is one of the four major professional sports leagues in North America, and the highest professional level of American football in the world. The NFL's 17-week regular season runs from early September to late December, with each team playing 16 games and having one bye week. Following the conclusion of the regular season, six teams from each conference (four division winners and two wild card teams) advance to the playoffs, a single-elimination tournament culminating in the Super Bowl, which is usually held in the first Sunday in February, and is played between the champions of the NFC and AFC.
