Answer by taking a quote from the following article:

Robert Montgomery Knight (born October 25, 1940) is a retired American basketball coach. Nicknamed "The General", Knight won 902 NCAA Division I men's college basketball games, the most all-time at the time of his retirement and currently third all-time, behind his former player and assistant coach Mike Krzyzewski of Duke University, and Jim Boeheim of Syracuse University. Knight is best known as the head coach of the Indiana Hoosiers from 1971 to 2000.

On March 14, 2000 (just before Indiana was to begin play in the NCAA tournament), the CNN Sports Illustrated network ran a piece on Knight in which former player Neil Reed claimed he had been choked by Knight during a 1997 practice. Knight denied the claims in the story. However, less than a month later, the network aired a tape of an Indiana practice from 1997 that appeared to show Knight placing his hand on the neck of Reed.  In response, Indiana University president Myles Brand announced that he had adopted a "zero tolerance" policy with regard to Knight's behavior. Later in the year, in September 2000, Indiana freshman Kent Harvey reportedly said, "Hey, Knight, what's up?" to Knight. According to Harvey, Knight then grabbed him by the arm and lectured him for not showing him respect, insisting that Harvey address him as either "Mr. Knight" or "Coach Knight" instead of simply "Knight." Brand stated that this incident was only one of numerous complaints that occurred after the zero-tolerance policy had been put into place. Brand asked Knight to resign on September 10, and when Knight refused, Brand relieved him of his coaching duties effective immediately. Knight's dismissal was met with outrage from students. That night, thousands of Indiana students marched from Indiana University's Assembly Hall to Brand's home, burning Brand in effigy.  Harvey was supported by some and vilified by many who claim he had intentionally set up Knight. Kent Harvey's stepfather, Mark Shaw, was a former Bloomington-area radio talk show host and Knight critic. On September 13, Knight said goodbye to a crowd of some 6,000 supporters in Dunn Meadow at Indiana University. He asked that they not hold a grudge against Harvey and that they continue to support the basketball team. Knight's firing made national headlines, including the cover of Sports Illustrated and around the clock coverage on ESPN.
