Kelvin Sampson's tenure as the head basketball coach at Indiana University came to an abrupt end in February 2008 when he resigned amid a major NCAA infractions scandal. The investigation revealed that Sampson and his coaching staff had committed major rules violations by making hundreds of impermissible telephone calls to recruits, violating restrictions tied to previous penalties stemming from his time at Oklahoma. The fallout led to severe institutional sanctions, the departure of his coaching staff, and a five-year show-cause penalty from the NCAA, prompting Sampson to transition temporarily to the NBA before rebuilding his legendary collegiate career at Houston.
