Episode 12:

A football family

1. Families come together at this time each year. People fly great distances to be with loved ones, and their busy lives come to a brief halt as they reflect on how good they've got it. They gather around the dinner table to eat, drink and give thanks. But also, they gather around the television -- to watch football.

2. This year, Jackie and Jack Harbaugh will travel from their suburban home in Mequon, Wis., to Baltimore, Md., to be close by as their two sons coach against each other at M&T Bank Stadium on Thanksgiving night for the first time. Jim will man the 49ers' sideline, while John leads the hometown Ravens.

3. "The NFL Season: A Biography" presented by SAP continues with a story about football, family, and a long coaching lineage that comes full circle beneath the Thursday night lights.
