Bobby Orr had six years of his prime ripped away by knee injuries he suffered with the Bruins.
The obvious answer to the question about Bobby Orr's knees is that the game-altering defenseman had at least another 5-6 great years ahead of him. The injuries piled up by the time he was 27, which for most players is the prime of their careers. Bruins fans of the 1970s were robbed of the chance to see a prime Orr, and modern day fans are left wondering how to compare him to the offensive boom of blueliners in this generation.
