Grinnell System

The Grinnell System, sometimes referred to as The System, is a fast-tempo style of basketball developed by coach Dave Arseneault at Grinnell College. It is a variation of the run-and-gun system popularized by coach Paul Westhead at Loyola Marymount University in the early 1980s. The Grinnell System relies on shooting three-point field goals, applying constant pressure with a full-court press, and substituting players frequently.

Arseneault in 1989 inherited a Grinnell program that had not had a winning season in 25 years. After a couple years of trying out traditional eight-player rotations, he felt Grinnell needed to change its basketball philosophy to rejuvenate the team and have more fun. Grinnell was a Division III school that did not offer athletic scholarships, and players that did not receive playing time were quitting. Arseneault developed the Grinnell System, which incorporated a dozen or more players in a game. According to his son, David Jr., who also played and later coached under his father at Grinnell, Arseneault did not believe the system would be a competitive strategy, but thought the increased scoring would develop a more positive environment, even if the team lost. Through 2012, Grinnell won five conference championships, advanced to the postseason 11 times, and led the nation in scoring at all levels of college basketball in 17 of the past 19 seasons.

Under the system, Grinnell guard Jack Taylor scored an NCAA-record 138 points in a 2012 game, and 109 in a 2013 game. Previously, Grinnell players Jeff Clement (77) and Griffin Lentsch (89) held the Division III scoring record.
