The National Football League (NFL) is the highest level of professional American football in the United States, and is considered the top professional American football league globally. It was formed by eleven teams in 1920 as the American Professional Football Association, with the league changing its name to the National Football League in 1922. The league currently consists of thirty-two teams from the United States. The league is divided evenly into two conferences – the American Football Conference (AFC) and National Football Conference (NFC), and each conference has four divisions that have four teams each, for a total of 16 teams in each conference. The NFL is an unincorporated 501(c)(6) association, a federal nonprofit designation, comprising its 32 teams.

The regular season is a seventeen-week schedule during which each team plays sixteen games and has one bye week. The season currently starts on the Thursday night in the first full week of September and runs weekly to late December or early January. At the end of each regular season, six teams from each conference (at least one from each division) play in the NFL playoffs, a twelve-team single-elimination tournament that culminates with the championship game, known as the Super Bowl. This game is held at a pre-selected site which is usually a city that hosts an NFL team.

The Football League, also known as the npower Football League for sponsorship reasons, is a league competition featuring professional association football clubs from England and Wales. Founded in 1888, it is the oldest such competition in world football. It was the top level football league in England from its foundation in the 19th century until 1992, when the top 22 clubs split away to form the Premier League (reduced to 20 clubs in 1995).

The Football League has been associated with a title sponsor since 1983. As this sponsor has changed over the years the league has been known in turn as the Canon League, the Today League, the Barclays League, the Endsleigh League, the Nationwide Football League and the Coca-Cola Football League, until the present sponsor npower was adopted in 2010, contracted until 2013.

Since 1995 it has had 72 clubs evenly divided into three divisions, which are known as The Championship, League One, and League Two. Promotion and relegation between these divisions is a central feature of the League and is further extended to allow the top Championship clubs to exchange places with the lowest placed clubs in the Premier League, and the bottom clubs of League Two to switch with the top clubs of the Football Conference, thus integrating the League into the English football league system. Although primarily a competition for English clubs, one club from Wales also takes part, while in the past Swansea City, Wrexham, Newport County, Merthyr Town and Aberdare Athletic have been members.

The Chicago Bears selected Tillman in the second round of the 2003 NFL Draft, making him the draft’s 35th overall pick. He became a starter after working very hard, and recorded 83 tackles and four interceptions during his first year with the Bears. However, an injury during his sophomore year temporarily grounded his career. Tillman rebounded the following year, recording 93 tackles and five interceptions. His efforts helped the Bears establish the league's best defense in 2005.
