Ted Williams, Yaz, Clemens, Rice, and Bird were all difficult personalities when playing (and I give credit to Yaz, Bird, and Rice for eventually coming to terms with it!) The Bruins had a maniacal following in Boston that filled the Garden every game for bad teams. Bobby Orr was the savior, and complemented his talent with tremendous class as a person. He is still beloved in Boston, where he raised his kids.
Russell SHOULD be revered as well, as he is every bit as gracious and classy a man, but suffers from the insular racism of the Boston fandom (not all of it, of course, but a sizable chunk.)
