Week 4 in college football was not good for certain schools in North Carolina (cheer up residents of Raleigh and Chapel Hill), and great for others around the country (here's looking at you, Michigan, for winning without a passing game).

USC made its Big Ten debut in a memorable matchup at the Big House, while Oklahoma had an SEC opener to forget against Tennessee.

Go ahead and pencil Tennessee into the College Football Playoff. The No. 6 Vols cleared their biggest hurdle yet by going on the road and opening SEC play with a 25-15 win against No. 15 Oklahoma, a likely cathartic moment for Sooners legend and current Tennessee coach Josh Heupel.
