He's avoided & refused to talk much about his career publicly, though there were some acrimonious statements made to a reporter well over a decade now pursuant to Eagleson's donation to York University in Toronto and the naming of a medical research facility after the latter (which was rescinded & returned by York, and Im sure shrinks would have plenty to say about that one). Several unauthorised biographies appearing over the years, the most recent being Stephen Brunts' In Search of Bobby Orr which without his participation did contain a fair amount of off the mark speculation. This will shed a lot more light on what went down from his perspective.
"My Game" by Orr and Mark Mulvoy is a wonderful book, highly recommend it. It was released in the early 70's, included interesting biographical content and some great insight into how the game (should be) played.
