We talk about his new book, "Rocket Men", which offers an inside look at the Black quarterbacks whose skill and grit transformed the NFL; and some of his other books including "The League", which focuses on the pioneering sportsmen who kept the league alive in the 1920s, 1930s, and 1940s, when its challenges were many and its survival was not guaranteed; and "The Streak" the book dedicated to Cal Ripken pursuit and eventually takeover of Lou Gehrig's Iron Man record. This is a great listen from a terrific storyteller.
