Eichorst was believed to be working closely with the NCAA during the joint inquiry into the athletic department, so his departure comes at a difficult time for both the department and the university, which is already dealing with a number of issues unrelated to the investigation, such as dwindling football attendance and major financial problems involving its highly touted medical school.
Eichorst addressed the scandal in a roundtable interview with Miami reporters on Nov. 1, 2011.
"I'm not making any excuses. I'm not asking anybody to feel sorry for me or anybody else," Eichorst said. "I've got a job to do and I'm only looking forward. I'm not looking backward."
Eichorst will receive a $750,000 retention bonus if he stays at Nebraska for five years. He'll pay a $2 million penalty if he leaves within a year. That penalty decreases $500,000 for each year he stays through the fifth year overseeing a 23-sport department with an $85 million annual budget.
"I asked him, 'If you were here five years from now, how would I be able to measure his success?' " Perlman said. "His response was, 'If the coaches and the student-athletes have been successful and nobody knows my name, it will be a success. The athletic department is all about the success of coaches and student-athletes.' "
