20. John Calipari
Calipari is like a cockroach. Numerous scandals arose over the years with his name linked yet he survives everything. It’s almost admirable how effective he is at keeping his nose clean. His most dramatic story was when Memphis tapped up Derrick Rose. They cheated his SAT results so that he could win a scholarship to the school.
An NCAA investigation revealed the truth but it also failed to incriminate Calipari in the process. Then there was the Marcus Camby ‘grocery money’ incident. While at UMass, Calipari allegedly allowed NBA agents to tap up Camby. Once again the NCAA cleared his name of any wrongdoing. Since settling down in Kentucky, Calipari has stayed very clean.
