For awhile there, Brandon Marshall seemed to be the latest in a long line of egotistical problem children who double as excellent wide receivers in the NFL. From Randy Moss to Terrell Owens to Santonio Holmes to Plaxico Burress … with all of them, their off-the-field issues rivaled their on-the-field exploits. But thanks to Ricky Williams, Marshall has helped to figure out what his problem is. Omar Kelly of the Sun-Sentinel broke the story this weekend:

After three months of treatment and therapy, psychological and neurological exams at Boston’s McLean Hospital, the training ground for Harvard University medical students, Marshall believes he’s finally at the root of his struggles.

He has been diagnosed with borderline personality disorder, or BPD …

BPD is a mental illness that studies say is more common than schizophrenia and bipolar disorder, but is rarely diagnosed because of misperceptions in the mental health community, and the challenges of providing a proper treatment plan.

The disorder is marked by difficulties with relationships and self-image and controlling moods and emotions.

Marshall caught his BPD at 27, and with any luck, it’s going to help him avoid future issues with his wife, teammates, and the law. Marshall’s last three years in Denver were so sick – he caught 307 passes in 46 games and scored 23 touchdowns – that he became one of the top five receivers in football. But he forced his way out of Denver – that was a very acrimonious divorce – and the Dolphins’ offense was garbage last year, so Marshall was something of an afterthought. Look at this downward trajectory of QBs he’s had: Jay Cutler, Kyle Orton, Chad Henne and now, maybe, Matt Moore.

Is there strong enough medication on the market for any stud who has to suffer through ducks from Henne or Moore? [Sun-Sentinel]
