During the National Championship game against Kentucky, the 3-point shooting rule is not present. This is historically accurate. The first time the NCAA experimented with the shot was 1945. The 3-point shot became popular during the 1967-68 American Basketball Association season. It was not used by the NCAA until 1986. The NBA adopted the shot during the 1979-80 season.
A few of the actors have played in other sports films. Derek Luke (Bobby Joe Hill) was in Friday Night Lights (2004) as James "Boobie" Miles, Damaine Radcliff (Willie "Scoops" Cager) was in Monday Night Mayhem (2002) as a New York Jets player, and Sam Jones III (Willie Worsley) was in Blue Mountain State (2010) as Craig Shilo.
