Very hard to believe. Multiple personality disorder is very hard to disguise. With how frequently he was examined by team physicians while in the NFL someone would have picked up on a problem.

My wife's a RN who worked psch. for years. MPD is extremely rare and often misdiagnosed by pschiatrists who are nuttier than their patients.
