What is a "show cause" list?
For example, let's say a coach gets in trouble for some kind of cheating or recruiting violation. I know this is a reach, but bear with me! :)
Anyway, there's a big problem at the university and the coach gets fired, while the university gets probation.
It is very possible that the coach will be put on the "show cause" list by the NCAA. That means that if another university wants to hire him, the new university has to make their case with the NCAA and "show cause" as to why the NCAA should allow the hire.
Kelvin Sampson (formerly Indiana basketball coach) is the first one that comes to mind.
Here's a bit more info from Sporting News:
Definition: The "Show Cause" penalty is perhaps the harshest in the NCAA's arsenal, as it essentially prevents a person from working in college basketball.
A show cause penalty -- usually with set duration -- may be handed down for a variety of reasons, but is most often used for coaches who commit NCAA violations relating to recruiting. For example, ex-Indiana coach was hit with a five-year show cause penalty stemming from improper phone calls made to recruits, and Ohio State coach Jim O'Brien faced the same penalty after making an under-the-table payment to a recruit.
Any school wishing to hire a coach under a "show cause" designation must appear before the NCAA infractions committee and potentially face new sanctions. No Division I athletic director has ever taken that step. As such, "show cause" usually amounts to a total ban from working at the college level for the duration of the penalty. For example, California coach Todd Bozeman was hit with an eight-year show cause penalty stemming from improper payments made to the family of one of his players. Ten years elapsed before Bozeman was able to find a job at the college level -- he's currently the head coach at Morgan State.
