One of the edges for the South over the North in their dominant era of college football? Coaching.

Nick Saban and Urban Meyer drove a new era of SEC excellence -- as natives of the North who spent much of their careers coaching in cold weather before turning around Alabama and Florida. How did the Big Ten let these Northern sons get away?

Lacking superstar coaching power, the North also fell short in ingenuity. That happened despite a revolution starting in the middle of Iowa -- before spreading through the rest of the country.

And then there was the money that wooed a Wisconsin winner like Bret Bielema -- a true Northerner headed South -- and he was just one example.

It's the coaching episode of The 25 Year Winter. Thanks for joining us.
