Familiarity often leads to volatility.
For the most part, conference play is here in college football, which means far fewer blowouts and a much greater likelihood for the type of upsets that can really shake up the rankings and change the season.
Eleven ranked teams play road games against unranked conference rivals this weekend, including No. 1 Alabama against an unbeaten Vanderbilt team that is feeling pretty good about itself after knocking off Kansas State last weekend.
No. 5 Southern California comes off an overtime win against Texas to visit maybe the most surprising team in the country, California (3-0). The Trojans will be a big test for an improved Bears defense.
The hottest spot on the slate is probably Iowa City, where No. 4 Penn State rolls into town. We only have to remember back to last season when the Hawkeyes upset Michigan, a result that helped Penn State win the Big Ten East, to know that Iowa is capable of putting up a detour on the road to the College Football Playoff.
Temple (plus 20 ½) at No. 21 South Florida
