I think the 1988 49ers are the greatest football team of all time. I know that sounds strange -- they lost six games. But if you go back and study that season, you'll notice that they played astounding football in pressure situations. In no-pressure situations, they tended to nap, and they could be beaten. But when everything hung in the balance, they could seemingly do anything. My book,TOM LANDRY AND BILL WALSH, emphasizes how both men shaped football as we see it today. But I spend a lot of time in Chapter 17 explaining why the 1988 49ers are the greatest team ever.
