His glaring narcissistic personality disorder is a non-starter for me. It is the root of his other red flags, like his baby mama drama, history of violence, and managerial malfunction. It is also a clarion that were his era at Auburn to end in termination, his bitterness and uncontrollable desire to destroy those who "wronged"/fired him would likely make Terry Bowden's sour grapes taste like honey in comparison. Owing to Sanders' media favor and connections, he could incinerate Auburn's program to a degree no other aggrieved coach has ever been capable of doing.
I think he is well capable of using any excuse to defame Auburn in retaliation, regardless of how valid or true. It is what narcissists do.
