We know what you’re thinking—why are those book nerds over at Kirkus pontificating about the best football books? Do they even watch football at Kirkus? Ahem—we’ll bypass that question to remind you that if it’s a book, we know whether it’s any good. This week, we highlight 10 gripping, insightful stories about the big egos, big money and big bruises at the heart of America’s national sport. You won’t get all 10 read before Sunday’s epic battle, but any of these titles will provide some nice perspective on why that little oval of pigskin—and the guys fighting and fumbling over it—capture our attention (even our attention).
