DALLAS — Everyone has an opinion of John Calipari. He's a pariah to some, successful only because of his ability to attract one-and-done stars destined for the NBA. They point to him as a scourge of college basketball, arguing that he's complicit — responsible, even — in stripping "student" from student-athletes. Then there are those who see him as an elite coach, the architect of successful programs at UMass, Memphis and now Kentucky.
