Responding to questions about the scandal that rocked college basketball and cost Rick Pitino his job at Louisville, Duke coach Mike Krzyzewski took aim at a business model he feels lacks necessary leadership and is not equipped to handle the recruiting landscape. “We don’t have a good model, a model that fits what’s happening in basketball, so college basketball’s going to have problems,” Krzyzewski, the winningest coach in Division I, told reporters at Duke’s media day Tuesday. “We in college have not changed as much as the landscape has changed. … When we recruit, the grassroots culture of basketball before we get them has changed dramatically. Before these kids ever come to us, we are not the only ones recruiting these youngsters. Talent is being recruited all the time in every shape and form. “We are not running this the way a billion-dollar industry should be run. We try and put a circle into a square, that’s what men’s college basketball is. It’s not a bad circle, it’s a great one, but it can’t be done like a square.” As part of an ongoing FBI investigation that began in 2015, four NCAA assistant coaches were indicted by federal authorities last week in a fraud and corruption scheme that alleged numerous instances of bribes to athletes. Federal prosecutors referred to the findings as “the dark underbelly of college athletics.”
