Besides first-round games at on-campus sites, the expanded 12-team College Football Playoff also serves up something now for this postseason: cold-weather northern venues as opposed to bowl games in warm, sunny climates. Whether that provides a home-field advantage for sixth-seeded Penn State, No. 7 seed Notre Dame and No. 8 Ohio State remains to be seen, but it’s a factor southern schools such No. 11 SMU and No. 9 Tennessee must prepare for. Tenth-seeded Indiana only has to travel a couple hundred miles north to South Bend but December football will be new to the Hoosiers, especially at No. 7 seed Notre Dame.
