Book excerpt: A Season on the Brink chronicles the basketball season that John Feinstein spent following the Indiana Hoosiers and their fiery coach, Bob Knight. Knight granted Feinstein an unprecedented inside look at college basketball -- with complete access to every moment of the season. Feinstein saw and heard it all -- practices, team meetings, strategy sessions, and mid-game huddles -- during Knight's struggle to avoid a losing season. A Season on the Brink not only captures the drama and pressure of big-time college basketball but paints a vivid portrait of a complex, brilliant coach walking a fine line between genius and madness.
