The Kansas coach's rough-edged approach is being called into question after linebacker Arist Wright complained to athletic director Lew Perkins about a recent incident where Mangino poked him in the chest.
Perkins then made the matter public by announcing an investigation into Mangino's behavior to see if it had become an ongoing theme within the program.
Several players — past and present — have since come forward to discuss Mangino's tough-love approach. Some have gone on the record, others have chosen to remain anonymous. Nearly all say Mangino has been out of line.
Dexton Fields, a receiver for the Jayhawks from 2004-08, called the complaints legitimate.
"It's been a long time that stuff has been happening and it had to surface," Fields told the Daily Kansan. "Of all the talent that KU has there, it had to be some other reason that KU isn't producing out on the field. It's been long overdue."
The Jayhawks have lost five in a row after winning their first five.
