Who knew that basketball has a storied Jewish past, or that a non-sports guy like me would ever read, no less enjoy, a book about baseball umpires, Bruce Weber’s “As They See ‘Em” (Scribner, 2009)? Maybe it’s because Passover is a time of miracles — or is that Chanukah? Or Purim? Or the entire sweep of Jewish history? No matter. We’re here to talk sports, a subject I now know a little more about.
