The school blames Sampson and his assistants for the messy phone-call scandal that has tarnished its men’s basketball program.

In a lengthy response to the NCAA’s newest major allegation, failure to monitor, the university accused Sampson and his staff of withholding information and concealing impermissible phone calls from the school’s compliance department.
