Gil reminded us all that Rav Soloveitchik זצ"ל was a Red Sox fan. That's hardly a surprise, given the fact that he lived, and was enmeshed in the fabric of Boston Jewish life for over sixty years.
I once noted in a comment that all of us in Boston knew the Rav was interested in the Sox. Over the years, though, I've encountered two versions of his level of enthusiasm. (I just can't recall the sources, at the moment.)
One story has it that the Rav once started a meeting in Boston with an excited cmment about some recent development with the team (Something like: וואס מיינט איר וועגען די רעד סאקס!).
The other, somewhat milder story, has it that ythe Rav explained his expertise in the team stats by the intense interest in the Red Sox on the part of the members of his family (a fact to which I can attest personally).
Truth to tell, I find this intense interest (and reaction) to the human side of great people and, a fortiori, Gedole Yisrael to be amazing. We almost invariably put them into procrustean beds, and are then amazed at their humanity. I find this regrettable. Great men are alway 3 (or 4) dimensional, not 2.
