Yes, it would have been real interesting had Bird and McHale not had serious injuries that prematurely ended their careers. But not only that, what if Len Bias did not O.D.? He did incredible things on the court. He could have been, at worst a Dominique Wilkins, or at best another Michael Jordan. You add a Bias to a healthy Celtics team and they win 3-4 more trophies.
